Simon, 64, gave an interview to Uncut magazine about the backward whispering, which prompted the U.K. tabloid The Sun to report that "David" is record executive David Geffen. But Simon's publicist disputed the theory. "The man's first name is David," she told CNNRadio, "but it could be one of many Davids." The Sun's theory revolves around the idea that Simon recorded the song to express displeasure at Geffen's signing of a rival, Joni Mitchell, for his record label, Asylum Records. Simon wasn't on Asylum, but her label, Elektra, merged with it in 1972, the year her album "No Secrets," containing "You're So Vain," was released. Geffen was put in charge of Elektra/Asylum. Simon is on record as being uncomfortable with Geffen. In Jac Holzman's oral history of the label, "Follow the Music," she said, "[The merger] was devastating. It was like I was a child of divorce -- my father was leaving me and now I had David Geffen as a stepfather." Simon has long played possum (to paraphrase one of her album titles) about the identity of the "You're So Vain" character, who travels by Lear Jet to witness an eclipse and, cuttingly, "probably think[s] this song is about you." At one point she said he was a composite; other times she has maintained he has certain letters in his name. NBC executive Dick Ebersol paid $50,000 at a charity auction for the revelation and a live performance of the song. Rumors have focused on Warren Beatty, Mick Jagger and Kris Kristofferson, among others. Beatty has said he believes it's about him. In a 2002 interview with CNN.com, Simon said that "You're So Vain" wasn't the only song about the man, whomever it might be. "There are always clues in other songs. The guy has repeatedly appeared in my songs," she said.
