Johnny Cash | A Concert Behind Prison Walls

The late Man in Black headlines this 1976 televised concert, shot inside the Tennessee State Prison and featuring post-hippie chanteuse Linda Ronstadt, country picker Roy Clark, and, rather incongruously, tuxedo-ed comedian Foster Brooks, whose '70s drunk act was often funny on, say, Dean Martin's Celebrity Roast, but seems a little wrong for an audience of felons.
