Just to see him come on the stage was an event. They had very high risers, and back a little bit, so he'd walk around behind the risers and right across the front of the stage to the podium, remember?
My impression was, he's walking as though he's made of glass, and if you should touch him he would just shatter apart. I don't know if it was an act or what, but it sure was effective.
My aunt had a season ticket for the Friday afternoon concerts, and I would go down for lessons. My lessons were Saturday morning.
