Having caught a good deal of his rehearsal on Friday before the fest, I observed he wants to be precisely prepared. He wanted to practice everything. Microphones, music stands, candles, lights, etc. would be included in this practice. I personally appreciated him wanting to prepare for us and be entertaining/engaging. He is a real professional and trouper. He could have rested on his laurels and we would have loved him anyway. But, I believe that he would not have accepted any unprofessionalism.
I'm sure it was v8ery strenuous for him getting in and out of the coffin as he did on Saturday as well and then doing his presentation. I'm bet he needed some much deserved rest. Even though very fit and fiddle, he is still in his eighties. I think he rocks for coming so I could see him in person.
