"The tape begins with an improvisational exercise in which Mariclare Costello acts as a puppet controlled by Dorothy Tristan. A discussion with members of American Theater Laboratory and author Tom Stone follows; sound is muffled and voices are difficult to hear. The actors rehearse a version of a scene called Jackie's testimony, from an untitled work in progress, in which the character of Jacqueline Kennedy gives testimony before the Warren Commission. A second version of the scene follows, in which the same three actors perform the dialogue while other members of American Theater Laboratory improvise riding on a train. Picture quality is very poor." . . . . . .
