Concert series entitled "Concerts on the Hill". Robert Hunter opened. From an attendee: That Caldwell College concert was memorable. Security was very hostile. Then halfway through the second set some crazed individual got on the stage leaping on it from behind the band and knocked over part of the drum kit. The band finished the song and left the stage. That explains the short set and no encore. Don't know what happened to the guy. He jumped into the area between the stage and a security fence which I think was full of cops. Wish I'd caught that on film but it happened too fast.
