Late to the party, but just a few corrections :
1: The song “Der Fuehrer’s Face” was written by Oliver Wallace specifically for the short. It was performed by Spike Jones after the short had become popular.
2: Disney had cut down on the amount of shorts that they put out on video, but surprisingly, when they do release them they are generally uncut. The cut versions are mostly the ones shown on television. (A notable exception in the recent release of “Melody Time.”) I’m discounting the releases like “DTV” or the “Sing-a-Long” series. They only one technically still in print is “The Spirit of Mickey” but there are still copies of the latest “Cartoon Classics” series still floating around in stores and online if you look around (including one which has the afore-mentioned “Clock Cleaners.”)
3: “Der Fuehrer’s Face,” although never having been released by Disney, can be had. Trust me. It’s all in who you know.
