Surviving members of the Grateful Dead, Bobby Weir, Bill Kreutzmann, and Mickey Hart, revisit the Great American Music Hall in San Francisco.

Mayer has historically played with the version of the band called Dead and Company, but Simpson has also subbed in a time or two. Sturgill is even set to play with the Dead Ahead rendition of the group at their upcoming “Dead Ahead Festival,” which will take place on the sandy beaches of Riviera Cancun, Mexico in early January.
