George Gershwin had a long-term relationship with Kay Swift. They met in 1925, when Kay was married. However, after Kay has marriage dissolved in 1934, because of her involvement with George, her affair with George lasted for around ten years in all. Gershwin frequently consulted Swift about his musicals and other work.
The song was used as the theme in Gershwin's last concert piece for piano and orchestra, the Variations on I Got Rhythm, written in 1934. The song has become symbolic of the Gershwins, of swing, and of the 1920s.
