The personnel count increased from seven to eight when banjo player Danny Barnes joined the group for two songs. Barnes, who appeared earlier in the evening as a part of show opener Robert Earl Keen’s band, released the CD “Pizza Box” last year on the Matthews-owned record label ATO.

Barnes sat in on “Cornbread” and was given a solo, though his spotlight was taken by Matthews, who hammed it up with an odd routine of posing and dancing to Barnes’ banjo picking.

Matthews yielded on the next song, when Barnes sang lead on his own tune “Road,” a rock number with a double-time bluegrass pace that the band approached with a bit of unsteadiness.
