Gov’t Mule is out on the road this fall, marching towards their tour finale for their annual Mule-O-Ween in NOLA.

Last week the Mule pulled into Knoxville, TN with supporting act Mike Campbell and The Dirty Knobs. Campbell joined Mule halfway through their set for a few tunes including a cover of Tom Petty’s “Breakdown.”

Thanks to vitaminrengery for the great footage!
