Lily Allen was one of twelve acts on the Parlophone label to have an exclusive record released for UKRecord Store Day 2010. The song chosen was "Back to the Start", with previous b-side "Kabul Shit" featuring again as the b-side to the single. It was released on a 7" vinyl only format, limited to 1,000 copies and was only available from selected independent music stores across the UK on 17 April 2010. The song could also be cherry-picked from the regular album download.
The song is about Lily’s relationship with her older sister, Sarah Owen. In the lyrics, Lily describes her hopes for Owen to forgive her, requesting that they try and go 'back to the start'. Lily explained to The Sun on 30 January 2009: "Sarah and I didn't get on for a long, long time. She cried when she heard that song and we are so close now. She finds it tricky with me being in the spotlight, though she'd never, ever want to go near a stage or perform herself. She's not jealous of me or anything like that. No. Not at all. The only thing she is envious of are my clothes."
