This past Monday (June 3) was The Rolling Stones' last concert of a three-night stay at the United Center (Home of the Chicago Bulls) in Chicago.
And every night the Stones welcomed a special guest to perform with them but on this last night The Rolling Stones' welcomed Taylor Swift as their special guest.
They sang "As Tears Go By," a song that Mich and Keith wrote for Mick's then girlfriend Marianne Faithful which was a top 10 hit in 1964.
Taylor tweeted about her amazing experience after the show.
