"My dad [Johnny Cash] went to the [Richard] Nixon White House and refused to sing "Welfare Cadillac" (instead performing the anti-war songs "The Ballad of Ira Hayes" and "Man in Black"). He protested the Vietnam War, but he went to perform for the troops with bombs dropping all around him. He had that kind of genius: a true artist's capacity for holding two opposing thoughts at once while being large enough to encompass all realities."
