I WILL ANSWER YOUR QUESTION....WHY DONT WE HAVE SINGERS LIKE THIS TODAY? GREAT GENIUS OF ANY TYPE COMES ALONG VERY RARELY. TRUE, THESE GUYS PERHAPS WORKED HARDER, BUT THEY WERE BLESSED WITH OUTSTANDING GENES, SAME AS NEWTON, JOHN VON NEUMANN, BEETHOVEN, MICHAEL DA VINCI, ...NO MATTER THE DEVOTION AND WORK ETHIC, IF YOU COME UP SHORT IN TERMS OF GENES, YOU MIGHT BE VERY GOOD, BUT NOT GREAT.
