"Ain't No More Cane on This Brazos" is a traditional prison work song of the Southern United States. The title refers to work assigned to prisoners sentenced to hard labor in Texas – to cut sugar cane along the banks of the Brazos River, where many of the state's prison farms were located in the late nineteenth and early twentieth centuries. "Ain't No More Cane" is featured in the film Festival Express, where Rick Danko, Janis Joplin, John "Marmaduke" Dawson, Jerry Garcia, Bob Weir, and various other musicians drunkenly sing it while on the train going to the next concert on the tour.
