That would have been a match made in Heaven. Karen and Barry.^^^ Impossible to tell, when we don’t know what the other material might have been or how strong. I do wonder though how long A&M would have gone on funding a duo who were not selling albums and were no longer commercial. That’s certainly the direction they were heading in by 1982, judging by the available material. I can almost hear Jerry Moss saying “Karen, maybe it’s time for another solo album, but this time let’s call Barry Gibb”.
Record labels won’t stay with the status quo forever, no matter how loyal the act is. They are in it to make money.
