Thinking back to when I was a kid I remember reading about this singer or that who was losing power to age. You know the stuff: "Sinatra's good, don't get me wrong. He just doesn't have the pipes anymore."
Young Jimmy Durante was fine but the old Schnozzola would wrap your heart around his finger. Ray Charles was christened "Genius" during the junk years but that later stuff burned, maybe even brighter.
Unfortunately most of our rock'n'roll stars don't live to get old. We were lucky enough to share those last Roy Orbison records but we'll never know what an old Buddy Holly would have given us. The power to bring us to tears or fill our hearts with joy and lust is in the music. Experience counts.
