For years, "You're So Vain" by Carly Simon provided one of the great mysteries in pop music -- just who was being addressed? "You probably think this song is about you" say the lyrics to this 1973 Billboard chart-topper -- with the intentional irony that yes, the song is, indeed about this person. But who?

In the '70s, Carly Simon was famous as a singer, songwriter and sex symbol. Not only was she born into a notable family, she was remarkably talented in her own right. Simon has enjoyed mega success throughout her career as a classical pianist and singer/songwriter. It wasn’t until years later, when she shared her memoir with the world, that we really had any insight into the real Carly Simon.
