On Friday, the Jerry Garcia Foundation in a partnership with Hard Rock Cafe San Francisco hosted a December Holiday concert to benefit WhyHunger and the Imagine There’s No Hunger campaign. The Hard Rock saw performances by several musicians including Grateful Dead guitarist Bob Weir who sat in with Rainbow Full of Sound.

Helmed by master of ceremonies Wavy Gravy, the event also included performances by Corby Pryor, Eric Nicholson, Greg Winser and Keystone Revisited. Video of Weir’s sit-in with Rainbow Full of Sound has surfaced and can be seen below.
