A week after performing with Carrie Underwood, The Rolling Stones have hit the stage with another country music star (if we're still calling her "country"), as the legendary rock band invited Taylor Swift to join them onstage for a rendition of "As Tears Go By" in Chicago.

Though it was only performed live for the first time in 2005, the song was among the first songs written together by bandmates Mick Jagger and Keith Richards, so one might imagine how it would be a big deal to Swift. For her part, Swift tweeted her excitement after the show: "Filing this under 'never in my wildest dreams'.Thank you @RollingStones for inviting me to Chicago to sing with you".
