Strike Up The Band (1940) was one of the many Rooney-Judy Garland movies of the era including the Andy Hardy series. Strike Up was not a Hardy film. In it, he played Jimmy Connors. The band was portrayed by the real-life Paul Whiteman Orchestra.
The Strip (1951) starred Rooney as jazz drummer Stanley Maxton. The pianist and nightclub owner in the film is played by actor William Demarest, known 15 years later as "Uncle Charley" on TV's My Three Sons. The song is the traditional jazz favorite "Ja-Da." A professional pianist almost surely dubbed in Demarest's playing.
