Taj Mahal sat in with The Rolling Stones at Chicago’s United Center last night. The blues guitarist—who was hot off an appearance with Umphrey’s McGee at Summer Camp—emerged partway through the Stones’ set for the band’s debut cover of Dave Dudley’s “Six Days on the Road.” Mahal has a long history with The Rolling Stones dating back to his involvement in the long-shelved 1968 film and concert The Rolling Stones Rock and Roll Circus. He also joined the group during 1997’s Bridges to Babylon tour.

In addition, onetime Stones guitarist Mick Taylor made his now regular appearances on “Midnight Rambler” and “(I Can’t Get No) Satisfaction,” while the Roosevelt University Chamber Singers provided the intro to “You Can’t Always Get What You Want.”

The Rolling Stones will return to the United Center on Friday.
