Bob Gruen     Arlo Guthrie, Bob Dylan and Dave Van Ronk Backstage at “Friends of Chile” Benefit concert,” the Felt Forum, New York City      1974

The “Friends of Chile” concert was organized by Phil Ochs.  It was intended to protest involvement by the United States in the overthrow of the democratically elected Socialist government of Salvador Allendein Chile and its replacement by the military dictatorship of Augusto Pinochet, and to provide assistance to survivors and refugees from Chile.  Performers at the concert included Phil Ochs, Arlo Guthrie, Pete Seeger, Dennis Hopper, Dave Van Ronk, Joan Baez, Melanie, several of the Beach Boys, Tom Rush and Bob Dylan.

Dylan was notoriously drunk off his ass at the show.  You can see him here getting himself into that condition.
