In the first part, Fred Astaire sings the legendary song to Ginger Rogers. The tune was written by the legendary songwriting brother duo, George and Ira Gershwin; sung in the 1937 film "Shall We Dance." The Brothers Gershwin wrote the other songs for the show/movie as well. In the second part, Fred and Ginger reprise the tune 12 years later in a dance number during their last film together, the "The Barkleys of Broadway".
