The original song composed by Frank Churchill for the cartoon, "Who's Afraid of the Big Bad Wolf?", was a best-selling single, mirroring the people's resolve against the "big bad wolf" of The Great Depression; the song actually became something of an anthem of the Great Depression. When the Nazis began expanding the boundaries of Germany in the years preceding World War II, the song was used to represent the complacency of the Western world in allowing Adolf Hitler to make considerable acquisitions of territory without going to war, and was notably used in Disney animations for the Canadian war effort.
