Granted the man gets around the stage a touch slower. But he still has 85% of the wonderful voice which has sung these beloved songs. He has taken good care of his health, and it shows.
Yes, he still sounds much like himself, which is pretty impressive for someone pushing 90. (I'm not entirely loving the new hairstyle, however, which is making him look a bit unkempt, IMO!)
His voice is wonderful, as always. It seems as though his left eye is causing him a bit of trouble during this concert, but hopefully it's just an itch.
