The Foo Fighters have continued to rock out despite frontman Dave Grohl’s broken leg, and at a recent show, the group added a talented fan to the mix. During Wednesday night’s concert in Edmonton, the Foos welcomed audience member Brian Roberts to the stage to perform Rush’s “Tom Sawyer.”

Grohl turned to the crowd to see if anyone knew the lyrics to the 1981 rock hit, as he’d forgotten them, and that’s when Roberts took the opportunity to jam in front of the Rexall Place audience. According to Uproxx, Roberts joined the band for some beers after the show to celebrate his killer performance, which you can watch below.

We bet Paul Rudd and Jason Segel’s I Love You, Man characters would’ve loved to lend a hand, too.
