Ed Sheeran just can’t avoid jumping onto an open stage, and on Saturday he popped up for a performance with the Rolling Stones.

Ed Sheeran just can’t pass by an open stage without getting on it, it seems. From popping up unexpectedly at weddings to joining a teenager singing in a mall for a duet, he’s one rocker who gathers no moss.

Which is why it was totally appropriate that Sheeran join The Rolling Stones on stage on Saturday during their Kansas City show at Arrowhead Stadium. He helped along on both guitar and vocals on their 1978 song, “Beast of Burden.”

It was clearly a highlight for Sheeran, who shared his enthusiasm on Instagram, writing “Just sung a song on stage with these ladz” and posting this picture:

While the Stones themselves posted a video of that Instagram-taking:

Clearly, playing with Sheeran was no burden at all.

The Rolling Stones invited one lucky fan to perform with them onstage at their Kansas City concert on Saturday: Ed Sheeran.

The Stones stopped at Arrowhead Stadium in Kansas City as part of their Zip Code Tour, and Sheeran joined them on acoustic guitar in a surprise performance of their hit “Beast of Burden.” He later posted a selfie with the band on Instagram, with the caption: “Just sung a song on stage with these ladz.”

Although the Stones said they decided on “Beast of Burden” after “days of discussion,” Sheeran and Mick Jagger joked earlier that they’d been rehearsing a cover of Fetty Wap’s “Trap Queen” instead. “It’s one of the favorite songs of this group,” Jagger said, “so we’re bashing away at the piano and guitar doing that.”
