<P> The song was co-written by Welch together with Paul Epworth who also produced the song which was recorded by Mark Rankin . The track features Tom' Moth' Monger on harp and Robert Ackroyd on guitar . During the verses, the song features some of the melody and lyrics (e.g. "How quickly the glamour fades") from Gang Gang Dance's song "House Jam". </P> <P> Florence described her inspiration behind the song: </P> <P> I'd written all these dark songs, and the label suggested we should have something that was a bit more upbeat . In the process of trying to do that, I realised maybe I was sacrificing something . So I had a really upbeat piano and drums, but the lyrics that came out were' This is the gift / It comes with a price / Who is the lamb / And who is the knife?' The rabbit heart is a reference to fear . I'm so afraid of what's about to happen . Of being in the spotlight . </P> <P> As part of the single's promotion, the band performed the song on The Jonathan Ross Show as well as in BBC Radio 1's Live Lounge . The single was also performed at numerous festivals across the United Kingdom throughout 2009, including Glastonbury, Electric Picnic, Brighton, T in the Park, Bestival and Reading, among others . </P>
