Written mostly by Stewart as a riposte to his wife's declaration that he did not tell her often enough that he loved her, "I'm Not in Love" was originally conceived as a bossa nova song played on guitars, but the other two members of the band, Kevin Godley and Lol Creme, disliked the track and it was abandoned. However, after hearing members of their staff continue to sing the melody around their studio, Stewart persuaded the group to give the song another chance, to which Godley replied that for the song to work it needed to be radically changed, and suggested that the band should try to create a new version using just voices.
