"Oh, Lady Be Good!" is a 1924 song by George and Ira Gershwin. It was introduced by Walter Catlett in the Broadway musical Lady, Be Good! written by Guy Bolton, Fred Thompson, and the Gershwin brothers and starring Fred and Adele Astaire. The song was also performed by the chorus in the film Lady Be Good (1941), although the film is unrelated to the musical. Recordings in 1925 were by Paul Whiteman, Carl Fenton, and Cliff Edwards. A 1947 recording of the song became a hit for Ella Fitzgerald, notable for her scat solo. For her album Ella Fitzgerald Sings the George and Ira Gershwin Songbook (1959), it was sung as a ballad arranged by Nelson Riddle.
