Lady, Be Good! (title sometimes presented with an exclamation point) is a musical written by Guy Bolton and Fred Thompson with music by George and lyrics by Ira Gershwin. It was first presented on Broadway in 1924; the West End production followed in 1926. The story of the musical is about a brother and sister who are out of money; both are eager to sacrifice themselves to help the other. This was the first Broadway collaboration of the Gershwin brothers, and the Astaire siblings play a brother-sister dance team.
