Vocalion Records is an American record label, originally founded by the Aeolian Company, a piano and organ manufacturer before being bought out by Brunswick in 1924.

[2] It sold exceptionally well, and the song became a blues standard for musicians from Memphis and Mississippi.

However, Columbia Broadcasting System (CBS) bought American Record Corporation (which operated the Vocalion label) in 1938, and in July 1940 they discontinued Vocalion, replacing it with the Okeh label.

[4] The City of London Phonograph & Gramophone Society CLPGS published a comprehensive database of British and Australian Vocalion records, including Broadcast, World Records and other labels used by the company in the 1920s and 1930s.

[5] The name Vocalion was resurrected in the late 1950s by American Decca as a budget label for back-catalog reissues.
