Pete Kelly's Blues

Producer, director and title character Jack Webb, with his band (Lee Marvin of note) in tow, shows up at the shindig thrown by Kansas City party girl Ivy (Janet Leigh, not a singer but a good sport) as she's coaxed to perform, tune by Jesse Greer and Benny Davis, in Pete Kelly's Blues, 1955.

Jack Webb, the producer, director and band-leader title character narrates about prohibition-era Kansas City rackets, then stumbles upon an improbably good local singer, Ella Fitzgerald in her cameo, with a tune she once recorded, by Milton Ager and Jack Yellen, in Pete Kelly's Blues, 1955.
