Wow. That's my overall impression: wow. Also, this show is long, in that great way. Both Christina and Justin perform normal length, so it's about twice as long as *NSYNC's Celebrity was.

Opening Act
( Black-Eyed Peas )
Part One
( Christina )
Part Two
( Justin )

To sum up: One of them would have been worth the ticket price, both of them made it a steal.
