It was 49 years ago today (January 6th, 1973) that Carly Simon scored her sole chart-topper to date, when “You're So Vain” hit Number One on the Billboard Hot 100 for the first of three weeks.
The song, which was produced by Richard Perry and included on Simon's 1972 third album No Secrets, featured solo Beatles sideman Klaus Voormann playing the distinctive bass part, Jim Gordon from Derek & The Dominos on drums, and Jimmy Ryan on guitars. Mick Jagger sang the instantly identifiable backing vocal.
Throughout the years Simon has refused to say publicly who exactly “You're So Vain” was written about and has sometimes said that it was a composite of several different men. She has confirmed that the second verse was indeed about actor Warren Beatty — but not the entire song.
