Although Carly Simon recorded You're So Vain way back in 1972, the mystery surrounding the subject of the song still smolders.

In a new version of You're So Vain, Carly whispers a name during an instrumental break; played backwards, it is clearly "David."

Rumors immediately flew that the David in question was record executive David Geffen. Carly's publicist disputed this theory.

Simon later told CNNRadio that the man's first name is David and "it could be one of many Davids."

The tabloid's theory centers around the notion that Carly recorded the song when she was miffed that David Geffen signed Joni Mitchell for his record label, Aslyum. Carly was with Elektra at the time and when it merged with Aslyum in 1972, the same year the You're So Vain track was released on the No Secrets album -- a rivalry was born

The highly discussed enigma has persisted and Carly has changed her tune over the years. Sometimes she has said that "David" is a composite and other times Simon has mentioned specific letters in his name throughout a song.

Although rumors circulated around megawatt stars like Warren Beatty, Mick Jagger and Kris Kristofferson, Carly indicated several years ago that song wasn't the only one about the man. "There are always clues in other songs. The guy has repeatedly appeared in my songs," she said.

So the mystery, like the song, plays on -- and that seems to be how Simon likes it.
