This was written by David Foster, Jay Graydon and Bill Champlin. In a Songfacts interview with Jay Graydon
he told the story: "David Foster produced an album for Jaye P. Morgan in 1976. It's a great record. It's available in Japan, and never did anything here, really. Then he was at Motown playing some songs with Jaye to try to get a deal over there.
He was in the middle of playing a song and he forgot the chorus, and he ad-libbed the chorus to 'After The Love Has Gone.' He comes over to my house, and we went into my little dinky studio. He sits down at the piano, and he says, 'Listen to this chorus.' He plays it, and I said, 'Hey, here's an idea for a verse.' And I went, 'da da dom, A major 7, da-D-minor-6, da da A major 7, bom ba da da da F-sharp minor.' And he just immediately continued on with that, and we had the whole song written in about half an hour/45 minutes.
We called Champlin: 'Bill, get over here, we need a lyric.' David was producing Champlin at the time. David recorded it with Champlin, maybe three different versions. He got one that he really liked, though. But then David was also writing with Maurice White for Earth, Wind & Fire for the I Am
album. He played the song for Maurice, and Maurice loved it. David called me and says, 'Hey, man, Earth, Wind & Fire wants to record it, but I don't want to tell Champlin that it's gonna have to get pulled off his record. Will you do it?' I said, 'I sure will.' (laughs) I called Bill and I said, 'Bill, here's the story.' And he says, 'I'm not an idiot, man.' (laughing) I said, 'I'm glad you say you're not an idiot. Because they say this thing's gonna be a single for sure. And this could be big.' Needless to say, that song still generates good money. It's unbelievable."
