Horace Horsecollar Performs (Lost Mickey Mouse Short,193?)

You might've heard of Mickey Mouse before. He's the most popular character Walt Disney created. In the 1920's and 30's, he had many cartoons during the years. One of the shorts, "Horace Horsecollar Performs" is kinda lost. Not much is known about this short. We do have a little bit of footage for this cartoon. It shows Horace Horsecollar playing instruments while Mickey composes.
