The thing that sticks in my mind the first few times I saw him live, was when he ended a drum solo with a hi-hat solo that went on and on. It was fun but a bit over the top. My ears were not happy by the end. In fact, the second time I saw him do it, I covered my ears for most of it.
The weirdest thing about the last two times I saw him was him singing "The Gambler", and getting the crowd to join in.
