Stuart Malina handles musical continuity and supervision. Movin' Out creators Billy Joel and Twyla Tharp won Tony Awards for orchestrations (with Stuart Malina) and choreography, respectively. The show, opened Oct. 24, 2002 on Broadway, launched its national tour from Detroit's Fisher Theatre, Jan. 27, 2004. James L. Nederlander, Hal Luftig, Scott E.

The bookless show, currently residing at Broadway's Richard Rodgers Theatre, uses Joel's song lyrics and Tharp's choreography to tell the story of five friends and lovers across three decades through love, war and loss. There is no dialogue and all songs are performed by the pianist-singer, who sings non-stop and heads an on-stage band during the show.
