The theme song from Paul Schrader’s mentally brutal 1978 working class thriller “Blue Collar.” One of the great forgotten films of the 1970s, with Richard Pryor, Harvey Keitel, and Yaphet Kotto. As Kotto’s Smokey character famously asserts: “They pit the lifers against the new boys; the young against the old; the black against the white. Everything they do is to keep us in our place.”
