Gov’t Mule is currently in the midst of touring in support of their new record Shout! and stopped in Louisville, KY last night. Tash Neal, guitarist in opening band The London Souls, joined the band on stage during their encore of “Rockin’ in the Free World” which featured a “Masters of War” intro, “Machine Gun” instrumental as well as “Third Stone From the Sun” teases. The London Souls are on tour in support of Mule through the October 5 show in Chicago, IL.

Mule is no stranger to guest spots on this tour, as they invited Tinsley Ellis and Ike Stubblefield to join them the other night in Atlanta.
