Strange goings-on in a department store, which is having a fire sale while it's on fire. Mice run a movie projector. In a live-action sequence, the singing Three X Sisters lead three bouncing-ball selections, the first Scottish, the second German, the last a bit of a black stereotype.
Unfortunately the movie Sing, Sisters, Sing! is not yet available on HBO Max.
