This is a great piece of comedic World War Two music. Spike Jones and His City Slickers released this in 1942 Spike Jones was sort of early Weird Al Jankovic, parodying popular songs of the day. In Der Fuhrer’s Face is a parody of the Horst Wessel song – a Nazi anthem of sorts. The song was very popular and even made an appearance in comic book form and was used in advertising to sell War Bonds.
The catchy tune was used in the famous Donald Duck cartoon (1943).
