Sam Smith wrote this song with Simon Aldred, who is the frontman of the rock band Cherry Ghost. Smith told Digital Spy
the story of the song. "We were in his living room having a cup of tea and I was completely entranced by the chords," he said.
"I immediately came up with that lyric, 'Leave your lover, leave him for me'. I remember feeling so proud that I got the word 'him' in. We just put that down as a demo and it took about an hour to write - then we went and got a bagel together!"
