Sweeney Todd: The Demon Barber of Fleet Street (often referred to simply as Sweeney Todd) is a 1979 musical with music and lyrics by Stephen Sondheim and book by Hugh Wheeler. It is based on the 1970 play Sweeney Todd by Christopher Bond. The character of Sweeney Todd first appeared in a Victorian penny dreadful titled The String of Pearls.

Sweeney Todd opened on Broadway in 1979 and in the West End in 1980. It won the Tony Award for Best Musical and Olivier Award for Best New Musical. It has been revived in many productions and inspired a film adaptation. A panel of five American critics assembled by New York magazine in 2011 described the musical as being among the three "greatest" musicals.Green, Jesse, Frank Rich, Nora Ephron, Jonathan Tunick, and George C.

Background The character Sweeney Todd originated in serialized Victorian popular fiction, known as penny dreadfuls. A story called The String of Pearls was published in a weekly magazine during the winter of 1846–47. Set in 1785, the story featured as its principal villain a certain Sweeney Todd and included all the plot elements used in later versions. The murderous barber's story was turned into a play before the ending had even been revealed in print. An expanded edition appeared in 1850, an American version in 1852, a new play in 1865. By the 1870s, Sweeney Todd was a familiar character to most Victorians."The story behind the legend of Sweeney Todd" . Timeout London. Retrieved on September 13, 2016.

The musical was based on Christopher Bond's 1970 play Sweeney Todd, which introduced a psychological backstory and motivation to Todd's crimes. In Bond's reincarnation of the character, Todd was the victim of a ruthless judge, who exiled him to Australia and raped his young wife, driving her mad. Stephen Sondheim first conceived of a musical version of the story in 1973, after he saw Bond's take on the story at Theatre Royal Stratford East."A Close Shave" .

Bond's sophisticated plot and language significantly elevated the lurid nature of the tale. Sondheim once observed, "It had a weight to it ... because [Bond] wrote certain characters in blank verse. He also infused into it plot elements from Jacobean tragedy and The Count of Monte Cristo. He was able to take all these disparate elements that had been in existence rather dully for a hundred and some-odd years and make them into a first-rate play.""Sondheim Notes: Sweeney Todd".

Sondheim felt that the addition of music would greatly increase the size of the drama, transforming it into a different theatrical experience, saying later: What I did to Chris' play is more than enhance it. I had a feeling it would be a new animal. The effect it had at Stratford East in London and the effect it had at the Uris Theater in New York are two entirely different effects, even though it's the same play. It was essentially charming over there because they don't take Sweeney Todd seriously. Our production was larger in scope. Hal Prince gave it an epic sense, a sense that this was a man of some size instead of just a nut case. The music helps to give it that dimension.

Music proved to be a key element behind the impact of Sweeney Todd on audiences. Over eighty percent of the production is set to music, either sung or underscoring dialogue. The score is one vast structure, each individual part meshing with others for the good of the entire musical machine. Never before or later in his work did Sondheim utilize music in such an exhaustive capacity to further the purposes of the drama.

Sondheim decided to pair one of the most nightmarish songs (Sweeney Todd's "Epiphany") with the comic-relief of "A Little Priest". This pair of songs at the end of Act I was the most significant musical addition which Sondheim made to Bond's version of the story. In the play, Sweeney Todd's mental collapse and the subsequent plan for Lovett's meat pies take place in less than half a page of dialogue, much too quickly to convey the full psychological impact, in the view of scholar Larry A. Brown. Sondheim's version more carefully reveals the developing ideas in Todd and Mrs. Lovett's demented minds. Sondheim often said that his Sweeney Todd was about obsession – and close friends seemed to instinctually agree. When Sondheim first played songs from an early version of the show for Judy Prince (wife of the show's director), she told him: "Oh God – I didn't know this was what [Sweeney Todd] was about. It's nothing to do with Grand Guignol. It's the story of your [own] life."

When Sondheim first brought the idea for the show to director Harold Prince, his frequent collaborator, Prince was uninterested, feeling it was a simple melodrama that was not very experimental structurally. However, Prince soon discovered a metaphor in which to set the show, making what Sondheim had originally envisioned as "a small horror piece" into a colossal portrait of the Industrial Revolution, and an examination of the general human condition of the time as it related to men like Todd. Said Sondheim, "Hal's metaphor is that the factory turns out Sweeney Todds. It turns out soulless, defeated, hopeless people. That's what the play's about to him; Sweeney Todd is a product of that age. I think it's not. Sweeney Todd is a man bent on personal revenge, the way we all are in one way or another, and it has nothing whatsoever to do with the time he lived in, as far as I'm concerned." However, Sondheim accepted Prince's vision as a different way to do the show, and as an opportunity to do the show on a large scale, knowing that small-scale productions could be done at any time.

On the stage of the Uris Theater in New York, this tale of horrors was transformed into a mountain of steel in motion. Prince's scenic metaphor for Sweeney Todd was a 19th-century iron foundry moved from Rhode Island and reassembled on the stage, which critic Jack Kroll aptly described as "part cathedral, part factory, part prison, that dwarfed and degraded the swarming denizens of the lower orders".

When it came to casting, Sondheim thought stage veteran Angela Lansbury would add some needed comedy to the grim tale as the lunatic Cockney shopkeeper, but Lansbury needed to be convinced. She was a star and, as she pointed out to Sondheim, "Your show is not called Nellie Lovett, it's called Sweeney Todd. And I'm the second banana." To convince her, Sondheim "auditioned", writing a couple of songs for her, including the macabre patter song, "A Little Priest". And he gave her the key to the character, saying, "I want Mrs. Lovett to have a music hall character." Lansbury, who had grown up in British music halls, immediately got it. "Not just music hall ... but dotty music hall", as she put it."Angela Lansbury: Sweeney Todd Demon Barber of Fleet Street" . Turner Classic Movies; retrieved September 13, 2016. After she was formally confirmed in the role, she relished the opportunity, saying that she loved "the extraordinary wit and intelligence of [Sondheim's] lyrics."Bonanno, Margaret Wander (1987).

Canadian actor and singer Len Cariou was Sondheim's personal choice to play the tortured barber."Len Cariou: Bringing the Gershwins Back to His Future" , Theater Pizzazz.com; retrieved September 13, 2016. In preparation for the role, Cariou (who was studying with a voice teacher at the time) asked Sondheim what kind of range he needed to have in the role. Cariou told him he was prepared to give Sondheim a couple of octaves to deal with, and Sondheim immediately replied, "That would be more than sufficient.""Blue Bloods star Len Cariou looks back fondly at Sweeney Todd" , CTV.ca; retrieved September 13, 2016.

With Prince absorbed in staging the mammoth production, Lansbury and Cariou were left largely to their own when it came to developing their characters. They worked together on all their scenes, both of them creative actors who were experienced in giving intense performances. "That cuckoo style of playing Mrs. Lovett, that was pretty much Angela ... She invented that character", Cariou said. She recalled, "I just ran with it. The wide-openness of my portrayal had to do with my sink or swim attitude toward it. I just figured hell, I've done everything else on Broadway, I might as well go with Mrs. Lovett."

It is said that on opening night Harold Clurman, the doyen of American theatre critics, rushed up to Schuyler Chapin, former general manager of the Metropolitan Opera, demanding to know why he had not put it on at the Met. To which Chapin replied: "I would have put it on like a shot if I'd had the opportunity. There would have been screams and yells but I wouldn't have given a damn. Because it is an opera. A modern American opera."

Synopsis The citizens of London, who act as a Greek chorus throughout the play, drop a body bag and pour ashes into a shallow grave. Sweeney Todd rises forth ("The Ballad of Sweeney Todd"), and introduces the drama.

Act I In 1846,Sweeney Todd 1982 video. young sailor Anthony Hope and the mysterious Sweeney Todd, whom Anthony has recently rescued at sea and befriended, dock in London. A beggar woman sexually solicits them, appearing to recognize Todd for a moment ("No Place Like London"), and Todd shoos her away. Todd obliquely relates some of his troubled past to Anthony: he was a naïve barber, and a corrupt judge who lusted after Todd's beautiful wife removed him as an obstacle ("The Barber and His Wife"). Leaving Anthony, Todd enters a meat pie shop on Fleet Street, where the owner, the slatternly widow Mrs. Lovett, laments the scarcity of meat and customers ("Worst Pies in London"). When Todd asks after the empty upstairs apartment, she reveals that its former tenant, Benjamin Barker, was transported for life based on false charges by Judge Turpin, who, along with his servant, Beadle Bamford, then lured Barker's wife Lucy to a masked ball at the Judge's home and raped her ("Poor Thing").

Todd's reaction reveals that he is himself Benjamin Barker. Promising to keep his secret, Mrs. Lovett explains that Lucy poisoned herself with arsenic and that their then-infant daughter, Johanna, became the Judge's ward. Todd swears revenge on the Judge and the Beadle, and Mrs. Lovett presents Todd with his old collection of sterling silver straight razors, which persuades Todd to take up his old profession ("My Friends" and "The Ballad of Sweeney Todd" – reprise). Elsewhere, Anthony spies a beautiful girl singing at her window ("Green Finch and Linnet Bird"), and the beggar woman tells him that her name is Johanna. Unaware that Johanna is his friend Todd's daughter, Anthony is immediately enamored ("Ah, Miss"), and he pledges to return for her, even after the judge and the Beadle threaten him and chase him away ("Johanna").

In the crowded London marketplace, flamboyant Italian barber Adolfo Pirelli and his simple-minded young assistant Tobias Ragg pitch a dramatic cure-all for hair loss ("Pirelli's Miracle Elixir"). Todd and Lovett soon arrive; as part of his plan to establish his new identity, Todd exposes the elixir as a sham, challenges Pirelli to a shaving competition and easily wins ("The Contest"), inviting the impressed Beadle for a free shave ("The Ballad of Sweeney Todd" – reprise 2). Several days later, Judge Turpin flagellates himself in a frenzy over a growing lust for Johanna, but instead resolves to marry her himself ("Johanna – Mea Culpa").
