Bob, thanks for your reply. The Caribbean feel is the shuffle beat from Superior Drummer that I wrote the song around. As for the phasing issue in the second verse, that may be the harmony being slightly out of tune with the lead. I'll check that out.
Robbie, it is indeed a love song. They say write what you know, and I have a personal connection to this story. I remember that Marx Bros. movie well, and I thank you for the comparison.
John, I'm happy you like the song. Your words always mean a lot to me.
