Original: "Rowdy Blues", a 1929 song credited to Kid Bailey, is disputed to have Brown on backup, or Brown himself using the name of Kid Bailey. Both "M & O Blues" and "Future Blues" appear on the album Son House & The Great Delta Blues Singers (1994), recorded between 1928 and 1930, on the Document Records label.
Simplified: A song called Rowdy blues was thought to have Brown playing on rhythm guitar since he played another song (Future Blues) on the same album (Son House & The Great Delta Blues Singers).
