Carly Simon

Taylor Swift's Red Tour rolled into Massachusetts over the weekend, and she had something special for the audience up her black-and-white striped sleeve: a surprise guest appearance from New England pop legend Carly Simon.

Marilyn Manson and Johnny Depp have collaborated on a song, which is interesting enough in itself. What's MORE interesting is that it's a version of Carly Simon's 'You're So Vain'!
