Well, it's nice to know that 5.1 DVD Audio magically restores forgotten lyrics and removes any uncomfortable ad lib moments. Does he dance better on DVD too?
I've seen him live and it's night and day but I think there's a reason why there's so little live material released. As I said in a review on Netflix for the Reality DVD: "at best, his live recordings simply make you wish you could have been there to see what it was really like. At their worst, they make you glad you weren't." Some people just don't translate well in certain settings and across certain mediums.
