Rodgers & Hart's On Your Toes, an improbable mix of gangsters, vaudeville and classical ballet, was the first musical to successfully integrate classical dance into the Broadway musical format. It has a book by George Abbott, Richard Rodgers and Lorenz Hart, music by Richard Rodgers, and lyrics by Lorenz Hart. The original production was choreographed by George Balanchine and starred Ray Bolger, Tamara Geva and Monty Woolley. It opened on April 11, 1936, at the Imperial Theatre and ran for 315 performances. Songs include "Glad to be Unhappy," "There's A Small Hotel" and the legendary ballet "Slaughter on Tenth Avenue." Former Encores! music director Rob Fisher returns for this production.
