Govt’ Mule’s summer tour rolled in to Louisville, KY’s Iroquois Amphitheater this evening. Blackberry Smoke have been on the road with Warren Haynes and company for the past few days and, as they have during their support run, joined the night’s headliners during their show.

To mark the end of their highly collaborative outing, all the members of Blackberry Smoke—Charlie Starr (lead vocals, guitar), Richard Turner (bass, vocals), Brit Turner (drums), Paul Jackson (guitar, vocals) and Brandon Still (keyboards)—emerged during Gov’t Mule’s encore for a cover of “One Way Out.” (Mule bassist Jorgen Carlsson sat out the number.) Then, Turner faded offstage and Carlsson returned for a show-closing take on “Whipping Post.”

The sit ins marked the end of a stretch of festive collaborations. On August 22 at Columbus, OH’s Express Live!, Starr sat in during Gov’t Mule’s encore for Crosby, Stills, Nash & Young’s “Ohio” and the Allman Brothers Band’s “Dreams” and, on August 24, he emerged for two other songs associated with the ABB at Cincinnati, OH’s PNC Pavilion. “Come & Go Blues” and “Statesboro Blues.” As previously reported, the members of Blackberry Smoke and a number of other guests joined Gov’t Mule in Nashville on Friday.

Gov’t Mule will perform at Salt Lake City, UT’s Red Buttle Garden on September 14 while Blackberry Smoke will appear at Memphis’ Delta Fair and Music Festival on September 1.
