First recorded by the rock group Badfinger, the song was composed by two of its members. Pete Ham wrote a song originally titled "If It's Love", but it had lacked a strong chorus. At the time of writing, the band shared residence with the Mojos at 7 Park Avenue in Golders Green. One evening, in the midst of the parties, songwriting, touring, in Golders Green, Ham and his girlfriend Beverly Tucker were about to go out for the evening. But just as they were leaving Tom Evans said he had an idea for a song – Ham said, "Not tonight, I've promised Bev." But she thought he would be wondering if he had done the right thing later, if he went out, – she told him – "Go into the studio, I'm fine about it"... He said, "Your mouth is smiling, but your eyes are sad." The song Ham wrote that night was called "If it's Love" and has the verse "Well I can't forget tomorrow, when I think of all my sorrow, I had you there but then I let you go, and now it's only fair that I should let you know... if it's love". But Ham wasn't happy with the chorus.
