The link between music and choreography is explored through rare footage of Fred Astaire, Gene Kelly (from his Broadway debut in "Pal Joey") and Cyd Charisse's first TV performance. Liza Minnelli reflects on Astaire and Kelly, both of whom she knew. Michael Feinstein also performs "Change Partners," "Singin' in the Rain," "Shall We Dance" and "Let's Face the Music and Dance."
