Show Girl is a musical that ran from Jul 2, 1929 to Oct 5, 1929 with a book by William Anthony McGuire, lyrics by Ira Gershwin and Gus Kahn, and music by George Gershwin. Its heroine, aspiring Broadway showgirl Dixie Dugan, was a character created by J. P. McEvoy and introduced in a novel first serialized in Liberty and then published in book form by Simon & Schuster in 1928.
The Broadway production was produced by Florenz Ziegfeld, directed by McGuire, and choreographed by Bobby Connolly, with ballet sequences, including one set to An American in Paris, by Albertina Rasch. Duke Ellington conducted the orchestra. It opened on July 2, 1929 at the Ziegfeld Theatre and ran for 111 performances. The cast included Ruby Keeler as Dixie, Jimmy Durante, Eddie Foy, Jr., Frank McHugh, and Nick Lucas.
Keeler's husband Al Jolson frequently sat in the audience and serenaded her with the show's closing number, "Liza (All the Clouds'll Roll Away)," from his seat. The song was featured in the 1946 biopic The Jolson Story.
