Butch Trucks joined ZZ Top on Saturday night during the band’s set in Nimes, FRA for a performance of “Tush,” which closed the show. ZZ Top performed at the Festival de Nimes in the arena that was once an old Roman arena as well as a bullring.

Trucks, who recounted the sit in on his Facebook page, commended the band (who started the same year as the ABB—1969) on still going strong after all these years. He called it “one of the most original sit ins ever” due to his setup which was just a snare, tom and cymbal.
