My aunt had a season ticket for the Friday afternoon concerts, and I would go down for lessons. My lessons were Saturday morning.
He was making all kinds of sounds apparently with his mouth, and shaking his head and I thought, gosh, is he trying to stop the orchestra? Is it all wrong? It was just unbelievable.
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.
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?
