Carly Simon's hit You're so Vain

Carly Simon poses between Paul and Linda McCartney, posted on a recent tweet by Carly.

Is she being vain, boasting of her association with the famous ex-Beatle?

I'll always remember how her taunting lyrics from "You're so Vain" came to my mind when many years ago I walked into the Yale Hotel with a friend to hear some music, and caught him admiring himself in the mirror that lined the wall. Thought about Carly's lyrics:

"You're so vain. You probably think this song is about you. Don't you? Don't you?" She was not above criticizing vanity in others. But then, who is?

But who was Carly addressing? Cat Stevens or Mick Jagger? Hopefully not James Taylor; she'd just married him. Kris Kristofferson maybe? It seems she'll never tell, but she enjoys keeping the rumours alive.
