Coincidentally I heard a replay of a 2010 interview with Billy Joel on Howard Stern the other day. Billy has a different story on the influence. Wiki had the quote, which is nice because my memory sucks...
I listened to Rag Doll and the only thing in common is the last lyric. You can also clearly hear the Uptown Girl melody. That said, I think Billy did rip off 10cc, but his memory is apparently worse than mine.
Wow you can hear so much. I hear three Billy Joel songs and the entirety of Bruce Springsteen’s 1970s catalogue.
And it’s a beautiful song on its own.
