Sebastian stated in an interview that he recorded his own vocals at his home, "The funny thing about that single is that I did all the vocals in my dining room in Australia and we sent it across to Andre Harris who did his thing on the track by adding his magic production touch." He also spoke about writing the song, "It's actually a completely original song that I kept going back to rewrite over and over again because, at first, the musician in me thought it was too simple in its structure... but then I realised that sometimes simplicity is the best way forward to keep things fun and hook-y."Artists - Guy Sebastian. adayonthegreen.com.au Archived from the original on 29 January 2012. Sebastian told The New Zealand Herald that it was based on songs he was hearing on the radio from the likes of David Guetta, and The Black Eyed Peas. "I'm not reinventing the wheel, not at all. I had that melody, and I could have gone so many ways with it. I could have produced an old-school soul album, but I went towards what you hear on the radio. I'm not going to lie, I listen to what's popular at the moment, and it's what I'm really liking as well."Smith, Jacqueline (2 December 2010). It's a Guy Sebastian thing. The New Zealand Herald.

Sebastian considered getting Eve on the song as quite a coup. He said she was on her way to London when she opened the email with the song attached and responded immediately, saying she would love to be involved. Eve said in an interview with Nova FM while she was in Australia to film the video, "I got an email, and when I heard it I was like 'hot song. Ok lets do it'. When asked if she did any research on Sebastian before agreeing to do the song she said "No. This is the thing. I don't really get into that. Like as an artist. It's more about the music, and if the song is hot, I'll deal with it. And I was like 'Ok, I'll do this song'."Eve talks about how she ended up singing with Guy Sebastian. Nova FM. dmgRadio Australia.
