Given the following context:

The film stars Don McKellar as Pokey Jones, an orphaned barber in a small town near Thunder Bay, who dreams of becoming a jazz musician. One morning, Jones discovers a frozen corpse in his backyard, and soon meets Jackie Bangs, a tough and mysterious roadie who claims the dead man is her brother.
Jackie's real intention is to use the body, a vagrant unknown to anyone in town, to smuggle stolen drugs into the United States. She convinces Pokey to use his parents' car, which has not been driven in decades, to drive her to New Orleans to bury her brother. So Jackie and Pokey set out along Highway 61, coffin strapped to the top of the car, and follow Bob Dylan's famous U.S. Highway 61 south through the heart of the United States. They are pursued by Mr. Skin, who believes he is Satan and wants to claim the body because the dead man sold Mr. Skin his soul.
Peter Breck is fourth-billed as Mr. Watson, the "stage-mom" father of three girls: Mississippi, Minnesota, and Louisiana. The film also includes cameo appearances by Tav Falco, Jello Biafra, and Art Bergmann.
The film's soundtrack album includes songs by Bourbon Tabernacle Choir, Rita Chiarelli, Nash the Slash, Acid Test, Jellyfishbabies, and Tom Jones. Nash the Slash also composed the film's instrumental score.
