ZZ Top wrapped up their string of dates with special openers Gov’t Mule last night at the Starlight in Kansas City. While collaborations on this run have been sparse thus far, things did pick up in that department last night as ZZ Top welcomed out Warren Haynes to close their show.

After an encore that included “La Grange” and “Tush,” the legendary rockers returned for a second encore with Haynes in tow for a cover of Elvis Presley’s “Jailhouse Rock” to close the show and tour together.

Gov’t Mule’s tour continues September 23 with a stop in Atlanta at the famed Tabernacle.
