The Avett Brothers took the name of the Outlaw Music Festival seriously on June 20, when they covered Merle Haggard’s “Mama Tried.”

The classic cowboy tune – which later became a favorite of the Grateful Dead – came on the tail end of the Avett’s single-set performance at Charlotte, NC’s PNC Music Pavilion.

They also welcomed Mickey Raphael to the stage for some nice harmonica work. A longtime member of Willie Nelson’s band, Raphael added some extra spice to the cover, which the Avetts have been playing fairly regularly since 2016.

Check out the band’s full setlist below:
