Celine singing "God Bless America" was a horrible casting decision. Sure, she has a good voice, but so does Kelly Clarkson and I think she would've gone over a bit better with the fans - you know, small town Texas girl hits it big and fulfills her dreams; real America- land of opportunity stuff.
Shania Twain didn't really seem to fit, and I don't think it went over well with the people in the stands.
Then again, last year's show with Bono singing "Beautiful Day" while the names of the WTC victims scrolls on two black screens is a tough act to follow.
At least we didn't get "Up With People".
