The Rolling Stones are still touring and still releasing albums. Meanwhile, the band has managed to stay relevant by using social media to keep its fans engaged and attracting some of the hottest new music stars in the business.

This weekend, The Rolling Stones rocked the MGM Grand in Las Vegas with a sold-out crowd. The band’s special guest of the night was none other than pop star Katy Perry, who sang a duet with Mick Jagger. The song the two sang – “Beast of Burden” – was chosen by fans using the Rolling Stones’ official mobile app.

Perry was obviously thrilled to sing and dance with the legendary band. She tweeted out her thanks to The Rolling Stones on Sunday, complete with pictures:
