John Mayer Sings ‘Ripple’ With Massive SF Crowd Gathered for Tribute to Grateful Dead Guitarist Bob Weir | Video

The stars came out for one more Saturday night to send off Bob Weir.

A public memorial for the Grateful Dead co-founder was held at Civic Center Plaza in San Francisco, drawing a massive sea of deadheads to say fare thee well to Weir, who died last Saturday at 78. Thousands attended the free event, including several members of Dead & Co. – the last of many iterations of the Grateful Dead fronted by Weir, who kept on truckin’ even after the 1995 death of his co-founder Jerry Garcia.
