16, 1937. The cast had been locked out of the Maxine Elliott Theatre by the Works Progress Administration, the government agency which had originally funded the production, so the cast and musicians walked with the audience to the nearby Venice. There, without costumes or sets, they performed the work concert-style, actors and musicians alike, sitting among the audience (to evade union restrictions on their performance) with Blitzstein narrating from the piano. In 1939, Leonard Bernstein led a revival of the play at Harvard, narrating from the piano just as Blitzstein had done. Blitzstein attended the performance, after which he and Bernstein became close friends; Bernstein would later say that Blitzstein's contribution to the American musical theatre was "incalculable". The 1999 film Cradle Will Rock was based on this event, though heavily embellished. In the film, Blitzstein (played by Hank Azaria) is portrayed as gaining inspiration through ghostly appearances by his idol Brecht and his late anorexic wife. Additional major compositions include the autobiographical radio song play I've Got the Tune, The Airborne Symphony (1946), Regina (1949), Reuben, Reuben (1955), and Juno (1959). At the time of his death Blitzstein was at work on Idiots First, a one-act opera based on the eponymous story by Bernard Malamud – intended to be part of a set of one-acters called Tales of Malamud – which Ned Rorem has called "his best work". This was followed by the work Blitzstein intended to be his magnum opus, a three-act opera commissioned by the Ford Foundation and optioned by the Metropolitan Opera entitled Sacco and Vanzetti. Both Tales of Malamud and Sacco and Vanzetti were completed posthumously, with the approval of Blitzstein's estate, by composer Leonard Lehrman. Lehrman's long-awaited Marc Blitzstein: A Bio-Bibliography, published in 2005 by Praeger, is the longest published biographical bibliography of any American composer at 645 pages. In 1958, Blitzstein was subpoenaed to appear before the U.S. House Committee on Un-American Activities (HUAC). Appearing first in a closed session, Blitzstein admitted his membership in the Communist Party (ending in 1949) and, challenging the right of HUAC to question him at all, refused to name names or cooperate any further. He was recalled for a further public session, but after a day sitting anxiously in a waiting room he was not called to testify. During a visit to Martinique in 1964, at the age of 58, Blitzstein was murdered by three sailors he
