Chris Robinson Brotherhood’s December 12 show at The Fillmore in San Francisco featured a special triple encore of New Riders of the Purple Sage covers with special guest Barry Sless.

The first two tunes, “Whatcha Gonna Do” and “Last Lonely Eagle,” were live debuts for the CRB (whose guitarist Neal Casal utilized Jerry Garcia’s “Wolf” during this show) prior to the finale of “Lonesome L.A. Cowboy.” Sless is a longtime collaborator of New Riders co-founder Dave Nelson.

CRB’s tour continues December 30 when they kick off their New Years run at Cervantes in Denver.
