Marc Blitzstein wrote The Cradle Will Rock, a pro-union musical staged by Orson Welles that was shut down by the Works Progress Administration in 1937 over its political content. He also translated and adapted Bertolt Brecht and Kurt Weill's The Threepenny Opera and Mother Courage and Her Children for American audiences, composed the opera Regina from Lillian Hellman's The Little Foxes, and wrote the Broadway musical Juno, based on Sean O'Casey's Juno and the Paycock.
