The 70’s were a period when most of the musicians that marked the rock and roll history emerged on the music scene. Among them was Carly Simon, who wrote the everlasting hit You’re So Vain.

She and her family lived in their house in Greenwich Village, New York, but young Simon loved spending most of her time at the estate in Stamford, Connecticut. During that time, she became close to baseball player Jackie Robinson who was a very good friend of the family. Jackie would take her to his games and fans even considered her the team’s mascot.

“Jackie even taught me how to bat lefty, though it never took,” Simon wrote in her memoir Boys in the Trees, published in 2015. “He always had the cutest look around the side of his mouth, as if he were thinking about what he was about to say before he said it.

Simon showed interest in music and soon after, she and her sister Lucy started performing together in Greenwich Village after they learned how to play the guitar by themselves. The duo was named The Simon Sisters and released three albums.

Once she started a solo career, Carly’s songs reached top numbers on the charts. Her single That’s the Way I’ve Always Heard It Should Be, which is part of her debut album Carly Simon released in 1971, was No. 10 on the Billboard Hot 100 list. Some of her most famous songs are Anticipation, Haven’t Got Time for the Pain, You Belong to Me, Coming Around Again, Mockingbird, Nobody Does It Better from the James Bond film The Spy Who Loved Me, and Jesse.

According to her, she wrote the hit Anticipation in 15 minutes while waiting for Cat Stevens at her place.

Being a new name in the world of music and releasing two very successful albums in a very short amount of time brought young Simon a Grammy Award for Best New Artist of the Year, and a nomination in the “Best Pop Female Vocalist” category.

However, it was the third song of her third album that made history. You’re So Vain is currently ranked at No. 92 on the list of Billboard’s Greatest Songs of All-Time and was voted No. 216 in RIAA’s Songs of the Century. In August 2014, the UK’s Official Charts Company crowned it the ultimate song of the 1970s.

But it remains a mystery until this day who that iconic song is about. At the time Simon was at the Trident Studios in London, England, recording it, Paul McCartney and Mick Jagger were present and Jagger sang the chorus, although he wasn’t credited for it. However, as it turned out, one of the people the hit was written for was the Rolling Stones front-man himself, and not Warren Beatty as many assumed.
