Okay, Ii've thought of a couple of possibilities which would work for 2 of the groups but not all three at once
For example: Songs about New York with "New York* State of Mind and Eyes of a *New York* Woman, but there wasn't a Rod song to fit in there.
Abd then there was the possibility of songs about ANY city with Rod's *DOWNTOWN* Train and Billy's *UPTOWN* Girl, but there was no song for BJ.
Then just as I was about to go to sleep a couple of those words back there jumped out at me and I will now venture my guess:
*Songs about parts of the body/anatomy*:
New York State of *MIND*-Billy Joel
*EYES* of a New York Woman
Hot *LEGS*-or-This old *HEART* of mine-Rod Stewart
(Something tells me that at least one of those songs did not make it to the top 40, but I think it's a good guess,
either way, don''t you? ;D)
Now I've got to hurry up and post this before my modem dies again....
