St. Jimmy at House of Blues is one of the few songs I distinctly remember without the assistance of a recording, simply because it blew me away. He was on fire, but in a good way, regardless if it was fast or not. You could tell he was incorporating some of the character from Broadway into his performance, and it was just so energetic. I was completely floored.
And then he ended it with "And that's my name... And I'm in the Rock and Roll Hall of Fame" and the crowd just lost it, myself included.
