Barbara, I think this simple change made a significant difference. This is what songwriting is all about, tweaking until it's joy. Prior to this, I would have remembered this singer. I don't say that to criticize the song as it is a commercially strong lyric. Just needed a memorable hook and it now has it. As a solution, I was thinking of an entirely new and different section, but I think your modest change was much better than what I had in mind. It works and it's memorable. Great song!
(With all that said, my mind is buzzing with production possibilities of this. Background choir on the hook, Al McKay type guitar part, etc.)
