'Guy Marks' (1923-1987) was an American actor, comedian, impressionist and singer who starred as The Baron in Fol-de-Rol.
Marks (b. Mario Scarpa) discovered he had a knack for doing impressions and sound effects at an early age. Eventually, this talent led him to the nightclub circuit, where he opened for A-list acts like Sammy Davis, Jr. and Eddie Fisher. Hollywood soon beckoned. First variety shows utilized him for his comedy routines and later Marks began dabbling in acting. In the 1970s, he had a hit with the novelty song "Loving You Has Made Me Bananas."
