No_Secrets_(Carly_Simon_album_-_cover_art)#13 – Carly Simon – “You’re So Vain” – (1972)

“You’re so Vain” has more legend around it than nearly any other song I can think of. She’s always said she’d never tell who it was about but only recently has she said that it is about three different people, with one of them being Warren Beatty. She’s claimed that it is definitely not about James Taylor… but who the other two people are remain a mystery. Carly has had other hits, but this is what she will always be known for.
