On the weekend of April 4–6, 1969, the Grateful Dead headlined at the Avalon Ballroom, the last rock show at the Avalon for almost 40 years. The final night was broadcast on KPFA-FM Berkeley. Great performances of “It's All Over Now Baby Blue”, “Death Don't Have No Mercy” and “The Other One”. The band was forced to conclude “Viola Lee Blues” acapella after the plug was pulled on the equipment for playing past the ballroom curfew!
