"You're So Vain" is a song written and performed by Carly Simon and released in November 1972. The song is a critical profile of a self-absorbed lover about whom Simon asserts "You're so vain, you probably think this song is about you." The title subject's identity has long been a matter of speculation, with Simon stating that the song refers to three men, only one of whom she has named publicly, actor Warren Beatty. The distinctive bass guitar intro is played by Klaus Voormann and the strings were arranged and orchestrated by Paul Buckmaster.
