From the wiki: “‘Steamroller Blues’ (a.k.a. ‘Steamroller’) is a blues parody written by James Taylor, that appeared on his 1970 album Sweet Baby James. It was intended to ‘mock’ the inauthentic blues bands (most always white) of the day.
“Rock journalist David Browne wrote that ‘[d]uring the Flying Machine days in the Village, Taylor had heard one too many pretentious white blues bands and wrote ‘Steamroller’ to mock them.” The song was also included on Taylor’s diamond-selling Greatest Hits 1976 compilation, using a live version recorded in August 1975 at the Universal Amphitheatre in Los Angeles.
