In her 1972 hit "You're So Vain," was Carly Simon talking about Warren Beatty, Kris Kristofferson or Mick Jagger? She's not telling, but she has launched a contest for filmmakers to produce a video for the song. (Apparently there's never been one before.) The winner gets their video shown at the Tribeca Film Festival and featured on AOL. Want to get in on it? Simon's got some footage on her site you can use to edit together an entry. Me, I'd just throw up a still photo of Beatty for three minutes.
So who do you think she's singing about? Simon herself offers up a few clues here.
