Although Johnny Cash spent most of his time in Arkansas and Tennessee, he experienced a revival of his career with the outlaw movement, especially after his live albums "At Folsom Prison" and "At San Quentin", both of which were recorded in prisons. Cash had working relationships with Nelson, Jennings and Kris Kristofferson in his later career, culminating in the formation of The Highwaymen; the four would record and perform as a supergroup in addition to their solo careers through the late 1990s. Cash had also been on good terms with several folk counterculture figures, a fact that irked Nashville and television executives (Cash hosted a variety show from 1969 to 1971). Like the other outlaw singers, he eschewed the polished Nashville look with a somewhat ragged (especially in later years), all-black outfit that inspired Cash's nickname, the "Man in Black".
