Symphony Hour is a 1942 American animated short film produced by Walt Disney Productions and released by RKO Radio Pictures.

The voice cast includes Walt Disney as Mickey, Billy Bletcher as Pete (as Sylvester Macaroni), and John McLeish as a radio announcer.

[2] The film marked the last theatrical appearance of Horace Horsecollar, Clarabelle Cow, and Clara Cluck for over 40 years, finally reappearing in Mickey's Christmas Carol (1983).

On the night of the performance, everyone is soon ready, except, of course, for Goofy, who accidentally drops all the instruments under an elevator, severely damaging them and thus rendering them unable to make proper musical sounds.

Macaroni is reduced to tears when the concert ends, believing his reputation to be ruined, but lightens up when he hears the thunderous applause from the audience.
