Did Paul McCartney specifically write Come And Get It for Badfinger? The Beatles version is quite similar, just less produced.

The Brothers Gibb wrote Chain Reaction for Diana Ross. Was'nt very good though.

Question.
Didn't NIN write a song for Johnny Cash?

No he just covered Hurt.

Joe Cardemone form The Icarus Line wrote the song slayer for Annie Hardy of Giant Drag. She didn't get big with it but The Icarus Line put it on their "Black Lives At The Golden Coast" and made a music video for Slayer.
