This clip is from episode 81 of The Great Space Coaster circa 2/2/1981. Danny is performed by Chris Gifford and Francine by Emily Bindiger. Unfortunately, the other performers are not identified in the credits; even the company group is not identified. However, based on other segments from other episodes, I believe these clowns were part of the Clyde Beatty & Cole Bros. combined circus. Roy (played by Ray Stephens) is notably absent. Often times the cast were split into different groups so various clips could be shot simultaneously.
