Trivia

 * In the Walt Disney Animation Studios building, when Mickey walks past by a photo of Walt Disney, a piano section of "Mickey Mouse March" from the 1950's Mickey Mouse Club, said to be his favorite song, can be heard. It is played by Richard M. Sherman on the very same piano in Walt's office.
