Carly Simon joins Taylor Swift onstage for You’re So Vain

Carly Simon joined Taylor Swift for the ultimate break-up song onstage in Massachusetts on Saturday night (27Jul13) when the pair teamed up for the veteran singer/songwriter’s You’re So Vain. Swift was performing in Foxborough when she gave fans a treat and brought out her special guest for a rendition of the 1972 classic.
And the country singer admitted she was just as intrigued about the subject of the song as everyone else, stating, “Before I bring out my special guest, I have this question that I’ve always, always had. I think a lot of you have probably had this question too, always wondered what the answer is. Who is this song, You’re So Vain by Carly Simon, written about?”
Simon has never been clear as to who the song is about, although experts believe it’s ex-boyfriend Warren Beatty.
Swift, it seems, had a blast onstage with one of her icons – after the show, she tweeted, “Got to sing You’re So Vain with Carly Simon at Gillette Stadium tonight!!!!! Unreal. I could not possibly look up to her more.”
