On This Day in 1973: Carly Simon’s Single Hit No. 1 Featuring Mick Jagger on Backing Vocals and a Mystery She Kept for Over 40 Years

Chart-Topping Success

On January 6, 1973, Carly Simon’s single You’re So Vain reached No. 1 on the U.S. Billboard Hot 100 chart, where it stayed at the top for three weeks. The song was released in November 1972 as the lead single from her third studio album, No Secrets, and became one of the most talked-about hits of the early 1970s. It also topped the Adult Contemporary chart and hit No. 1 in Canada, Australia and New Zealand, while reaching the top five in Ireland.

The recording featured several notable musicians. Bassist Klaus Voormann, known for his work with the Beatles and for designing the cover of Revolver, performed the distinctive bass line. Jim Gordon from Derek & The Dominos played drums, and guitarist Jimmy Ryan added key parts. The track’s backing vocals included an uncredited turn by Rolling Stones singer Mick Jagger, who happened to be in the London studio during the session. Simon later explained, “I was in London, it was 1972 and he happened to call at the studio… why don’t you come down and sing with us?”

A Song With a Lasting Mystery

For decades, You’re So Vain stirred questions about whom the lyrics described. The chorus line “You’re so vain, you probably think this song is about you” became part of pop culture, as fans and journalists tried to guess the subject. Simon often refused to name the person, saying only that the song was about several people rather than one.

More than forty years later, she offered a partial answer. In a 2015 interview, Simon confirmed that the song’s second verse refers to actor Warren Beatty. “I have confirmed that the second verse is Warren,” she told People magazine, adding that Beatty “thinks the whole thing is about him.” However, she also stressed that only that verse is about him, and the first and third verses were about other men in her life at the time.

Simon has avoided revealing the full list of inspirations. Asked if she would name them, she said, “I don’t think so… at least until they know it’s about them.” The lyric remains a clever tease, reflecting both personal experience and public fascination.

Impact and Recognition

You’re So Vain helped elevate Simon’s career and remains her signature song. It earned Grammy nominations, including Record of the Year and Song of the Year, and was later inducted into the Grammy Hall of Fame. The song also helped No Secrets reach No. 1 on the Billboard 200, boosting Simon’s visibility as a singer-songwriter in a crowded musical era.

The track’s blend of sharp lyrics, memorable melody and high-profile backing voices has kept it in the public ear for decades. Even with partial answers about its origins, the song’s mystery continues to spark interest among new listeners.
