"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. Willie Brown does his song "Future Blues" on the album Son House & The Great Delta Blues Singers (1994), recorded between 1928 and 1930, on the Document Records label.
David Evans has reconstructed the early biography of a Willie Brown living in Drew, Mississippi, until 1929. He was married by 1911 to a proficient guitarist named Josie Mills. He is recalled as singing and playing guitar with Charley Patton and others in the neighbourhood of Drew. Informants with conflicting memories led Gayle Dean Wardlow and Steve Calt to conclude that this was a different Willie Brown. Evans rejects this, believing that the singing and guitar style of the 1931 recordings is clearly in the tradition of other performers from Drew such as Charley Patton, Tommy Johnson, Kid Bailey, Howling Wolf and artists recorded non-commercially.
Alan Lomax added further confusion in 1993, suggesting that the William Brown he recorded in Arkansas in 1942 was the same man as the Paramount artist. The recording was for a joint project between Fisk University and the Library of Congress documenting the music of Coahoma County, Mississippi in 1941 and 1942. Writing over fifty years later, Lomax forgot that he had actually recorded Willie the previous summer with Son House, Fiddlin' Joe Martin and Leroy Williams. Brown played second guitar on three performances by the whole band, and recorded one solo, "Make Me A Pallet On The Floor".
The later biography is clear. Willie Brown, the Paramount artist, lived in Robinsonville, Mississippi from 1929 and moved to Lake Cormorant, Mississippi by 1935. He performed occasionally with Charley Patton, and continually with Son House until his death. After this, House ceased performing until his "rediscovery" in 1964.
