Jamgrass legends Leftover Salmon brought their wares to San Francisco, CA last night, hitting the famed The Fillmore venue along their winter tour. The stop in San Francisco had a surprise visitor, however, as the band called upon Bill Kreutzmann to lend a hand on an appropriate Grateful Dead cover.

Kreutzmann joined the fold for a great rendition of “Playing In The Band,” a hitting choice considering he was literally playing in the band. Check out a video of the performance below, courtesy of Benjy Eisen.

Kreutzmann also played on “New Speedway Boogie” with Salmon, adding his drums to the celebratory performance. The show was also held on the 50th anniversary of the Human Be In, which took place in San Francisco, and the energy of that historic moment was felt by all in attendance.
