This is a short clip from an early b&w Mickey Mouse cartoon called "The Opry House". It shows the first time in an animated film where the "Hungarian Rhapsody No. 2 in C-sharp minor" is used. This tune would become famous in animation history due to later cartoons such as "Rhapsody in Rivets", "The Cat Concerto" and "Rhapsody Rabbit". And if you watch closely, you'll see that "Rhapsody Rabbit" borrowed heavily upon this performance by Mickey, as they use the same general situation and have a number of similar gags
