Graham Chapman was doing a radio interview in the Baltimore/Washington DC area and asked a radio staffer what was happening locally. She replied that she was working on a film and invited him to the set. He showed up at 3am at the Reed Street set. Chapman and the director quickly improvised and shot a scene together. But when the film came back from the lab, a thick emulsion scratch left his work unusable in the original cut. However, during a re-edit, the filmmakers discovered that his footage was easily repaired with current technology and he has been added to the new cut.
