Mickey guest-directs a radio orchestra. The sponsor loves the rehearsal, but come the actual performance, Goofy drops all the instruments under an elevator, so they sound like toys. The sponsor hates it, but the audience loves it anyway.
Unfortunately the movie Symphony Hour is not yet available on HBO Max.
