My sister-in-law got us tickets to go see him about 10 years ago. I went, thinking that the "concert" was just going to be him dancing around and goofing off to pre-recorded music and things like that. WOW, was I blown out of the water.
He has one of the tightest bands I've ever heard. I mean, they played live and hit everything almost perfectly. I later find out he's been touring with the same people for decades, and they are at the top of their game musically. I went in being a fan of his music, but came out with so much respect for him as just a shear musician.
