This is the Rainbow Christmas Special episode from 1987 in which the gang put on a pantomime. The Bad Baron Bungle and his wicked schemes make life difficult for Dame Geoffrey, Georgie Porgie (George), Tommy Tucker (Zippy) and Jack (Jane). But everything works out fine in the end and Baron Bungle gets his comeuppance. Then Santa Claus drops by to join everyone in singing "Happy Christmas Everybody".
