So many things come to mind when we think of Johnny Cash. There is the distinctive sound of his early Sun Records hits; the somber image he cultivated as the Man in Black; his devotion to Christianity and his struggle with drugs; his compassion for those forgotten by society; and the songs -- "Ring of Fire" "Folsom Prison Blues," "Five Feet High and Rising," "Sunday Morning Coming Down," "I Walk the Line," "Hurt," "I've Been Everywhere" -- just to name a few.
