At the home of Viennese composer Johann Strauss lived Johann Mouse. Whenever the composer played his waltzes, the mouse would dance to the music, unable to control himself. One day, when Strauss was away, the house cat played his master's music. When word got out about a piano-playing cat and a dancing mouse, they were commanded to perform for the emperor.
Unfortunately the movie Johann Mouse is not yet available on Disney Plus.
