Ballet in one act with choreography by Robbins, music by Bernstein, set by Oliver Smith, and costumes by Kermit Love. Premiered 19 Apr. 1944 by Ballet Theatre at the Metropolitan Opera House, New York, with Lang, Kriza, Robbins, Bentley, and Reed. This seminal all-American ballet portrays three sailors on leave in New York, who meet two girls on a hot summer night. It was Robbins's first ballet, and an instant hit. With its cast of brash and lively modern characters, its mix of classical and vernacular dance, it influenced not only American ballet but also theatre and cinema and was turned into the musical On the Town (mus. Bernstein, chor. Robbins, dir. George Abbott, 1944) and later a film of the same title (1949). Robbins revived the ballet for New York City Ballet in 1980 and it was also staged for Dance Theatre of Harlem in 1985. New versions have been choreographed by F. Marteny (Graz, 1969, and Ballet of Marseilles, 1971) and T. Schilling (E. Berlin 1971).
