The link from Villan to Carly Simon's "You're So Vain" page gives a final answer from Carly herself:Now, there's a woman with class.
USA Today - June, 2005
"It's about Mark Felt!" Simon, 59, joked by phone Wednesday from her home in Martha's Vineyard, referring to the former FBI official who has said he was Deep Throat. You're So Vain was a No. 1 hit in January 1973, six months after the Watergate break-in that led to President Nixon's downfall.
But unlike the Watergate principals, Simon says she'll never reveal the answer, not even when she or the song's subject dies. "I don't see why I ever would. What would it advance? I wrote that song in the days when people kept confidences to themselves, whereas now, people expose them so easily and readily for the benefit of their next movie sale."
She finds it "bizarre" that fans are still speculating about her lyrics three decades later. "If people knew who it was to begin with, it might not have become a hit."
