Henry Thomas recorded “Blue-Doze Blues” on the same day in 1928 as “Don’t Ease Me In” and “Fishing Blues”.
The most famous cover is by Canned Heat who played it as Woodstock in 1969.
“Bull-Doze Blues”, another of Thomas’s Vocalion recordings, was reworked by the pianist Johnny Miller in 1927, who rewrote the words and gave it to Wingy Manone, who recorded two versions titled “Up the Country” in December 1927 for Columbia and September 1930 for Champion Records. Except in jazz circles, it remained an obscure blues number until blues-rock group Canned Heat recorded “Going Up the Country“. Though rearranged, the Canned Heat song is musically the same, down to a faithful rendition of Thomas’s quill solos by Jim Horn. The lyrics also borrow from Blind Willie McTell’s “Statesboro Blues” (1928). Fellow band member Alan “Blind Owl” Wilson rewrote the lyrics entirely and received credit on the song’s original release in 1968 on Canned Heat’s third album, Living the Blues. The next year, the group played at the Woodstock Festival. The live performance of “Going Up the Country” was featured in the motion picture Woodstock and appeared as the second cut on the soundtrack album.
