This was filmed in Chicago 1978, Papa John Creach playing with Grace Slick and Hot Tuna. "I filmed from stage side one roll of Reg 8mm black and white. As the film ran out of the second side of the film, someone from security tapped me on shoulder and demanded that I give him the film. I started fast talking and told him that I would stop filming, he still demanded the film. I then opened the camera and showed him that there was no film left in the camera. That seemed to please him and he left." — DA
