LOVINGLY RETAINED in the bowels of all newspaper libraries and, I imagine, in thousands of crammed scrapbooks throughout the world, is a certain photograph of a certain man in the prime of his very special life - a man who has become a hero to the uncertain and the simplistic, to the doubting and the desperate, to the young and the restless. Originally known as Chaim Witz, then as Chaim Klein, then as Gene Klein, this man is now revered as Gene Simmons.
