The Rolling Stones brought their European tour to London’s Twinckenham Stadium on Tuesday night, and the legendary rockers welcomed singer-songwriter James Bay for one of their classics.

Bay, who served as supporting act for the night, emerged near the middle of the Stones’ set for “Beast of Burden,” on which he shared vocals with Mick Jagger. Watch a video of the performance above.

As Rolling Stone notes, Bay welcomed Rolling Stones guitarist Ronnie Wood for a cover of Faces’ “(You Know) I’m Losing You” a couple years ago, and Bay took to Instagram after Tuesday’s show to express gratitude toward the band, writing, “This band have probably shaped the way I make music and perform more than anyone else. Their relentless passion and energy onstage is so inspiring. I can’t believe last night was real.”
