L'Opéra de quat'sous
Among Capalbo's notable productions were a revival of "The Threepenny Opera", which was a major Off-Broadway success, and the 1957 premiere of "A Moon for the Misbegotten". He won a Special Tony Award in 1956 for "The Threepenny Opera" and another in 1957 for "The Potting Shed". He also directed the world premiere of Robert Kurka's "The Good Soldier Schweik" for the New York City Opera at Lincoln Center in 1958.
