Very Interesting!
Some, but not all of what he presented, was new to me and I'm glad to have seen it. Now I only need to remember it when I need it!?!?
He was a little hard to understand in a couple of key spots, so darn, guess I'll just have to watch it again!
Zee wert listening cloze enuff. 
My earbones done did the best they could.
Perhaps it was my brain that was lagging behind?!?!
I should add that I'm really not going to mind watching it again and trying to "listen clozer enuff" to pick up what I might have missed in the first go around!
