The Cat and the Tune (1977)

A flute playing cat leads a band composed of animals. The animated images accompany a recording of 'Eye Level'. Cats, mice, tigers, monkeys, camels, penguins, birds, as well as, a bear, a cheetah, an elephant, and a seagull appear with stop-clock precision to play instruments featured in the recording at appropriate points in the sound track. The flute-playing cat vies with a lion bandmaster in leading the band.

Unfortunately the movie The Cat and the Tune is not yet available on HBO Max.
