Saturday night the recently displaced Radiators made an appearance at San Franciscos Great American Music Hall. Near the end of the groups first set, hometown hero Bob Weir emerged adding guitar to Waiting For The Rain and Jump Into The Fire. Weir then took command of the microphone providing vocals on Little Red Rooster, The Race Is On and Deal. A night later the RADS also performed a stealth show as Wimawoma at Mill Valley, CAs Big River Sweetwater. Weir once again appeared with the group during its first set joining for an handful of numbers including Bob Dylan’s Maggies Farm and Big River. The Radiators tour continues tomorrow at Santa Cruz, CAs Moe’s Alley.
