Of all the American songs that came out of World War II, Hitler Blues is one the very few that blames Hitler for his mistreatment of the Jews. This gritty 1942 recording by Huddie William Leadbetter (Lead Belly) is the definitive version, but is not the original.
Hitler Blues– it’s actually not a blues but a folk ballad– was composed by the Texas piano player, Roosevelt Thomas “Grey Ghost” Williams, and recorded by him in 1940. Considering the lyrics, it’s worth noting that this was a year before the United States entered the war.
