The Rolling Stones kicked off Milwaukee’s Summerfest with a show at Marcus Amphitheater where they jammed with Buddy Guy. Following the first few tunes, the band welcomed out Guy for a cover of Muddy Waters’ “Champagne & Reefer.” After Guy’s departure, the band busted out “Doo Doo Doo Doo Doo (Heartbreaker)” for the first time since 2007.

Frontman Mick Jagger took to Twitter to post a picture of him with Guy backstage prior to the performance as well as a video which you can watch here.

The Stones’ Zip Code tour continues June 27 in Kansas City, MO at Arrowhead Stadium.
