J Dudley, no need to be rude, but, Carrie does that in almost all of her live songs, and that is why I like her. She has an amazing voice! I am a teenager, and she is my idol :)
I am searching youtube for a really glorious version of our beloved National Anthem to use as an my alarm in the mornings, I may have just found it. As an aside almost anyone singing this with heart and making a true effort will always leave me with moist eyes. Beautiful song.
