I've seen it three times now. Once in Epcot on a great day. Once in Epcot on a rainy day. And then 2 weeks ago in Baltimore I got to see the full show. Talk about wow. I went with other band nerds like myself, and the only way to describe it would be borderline orgasmic. "Ooohhhhh! Oh my God, Oh my God! Did you see that?"
It is such an awesome show. Be sure to go out to the lobby during the intermission to see the whole show.
If you buy the CD, VHS, or DVD, I sugguest getting it from shopPBS.com it's a little cheaper that way.
BTW one of the former JAMMators is in the touring show that came here.
