Carly Simon has finally ended the 38 year guessing fame over the subject of her hit song, "You're So Vain".  Is it:

A) Mick Jagger

B) Cat Stevens

C) Warren Beatty 

D) David Geffen

You didn't pick D did you?  But the "Sun" reports Simon solved the riddle by whispering David Geffen's name backwards in a reworked version of the 1972 song for her new album "Never Been Gone" which comes out next week.  When she wrote the song, Geffen was head of Elektra Records.

Mick Jagger sang on the song.  Warren Beatty was an obvious choice. And Cat Stevens was the subject of "Anticipation".  David Geffen?  That kind of came out of nowhere.
