• La Roux are singer Elly Jackson and her studio partner Ben Langmaid. Jackson started off writing songs with an acoustic guitar, before switching to the synthesiser. This song about the heartache of love gone wrong is the only one on La Roux that she retained from her acoustic days. The singer told Troubled Diva that it "was the first song me and Ben ever wrote together on guitar."
• Jackson told Troubled Diva that despite this change in style, the pair haven't changed the way they write songs. Said Jackson: "We don't write on guitar anymore, but we still go through the same process. You get four or five chords that you really like, and then you start humming over them. And you find some lyrics, and find a melody, and go from there really. So it's the same process, but on a different instrument."
