Probably the most famous country singer in the world, Johnny Cash - The Man in black, survived the highs and the lows of a glittering career spanning three decades. Cash was the man who new what life was all about: he lived it on so many levels and in so many strained circumstances. he experienced the lonely sound that the clanging of a cell door makes behind you and, because of his deep abiding love of helping those less fortunate than himself, he returned to the stony confines of prisons like San Quentin and Folsom to entertain the inmates with songs that meant so much to the prisoners of crime or conscience, whoever they may be. Of his talent, Johnny Cash was humble, he called it a gift from god. he said that it was just a 'thing' he had.
