I agree somewhat with Dr Winston. Too many times celebrity pop stars modify the rhythm or the notes of the National Anthem to suit their own particular style and thus make the focus on themselves rather than on the song. I suspect some also do this to disguise their lack of vocal range and inability to hit certain high notes. But overall I felt that Lady GaGa's embellishments were rather minor and served to enhance the spirit of the song rather than detracting from it.
I thought she was terrific, but that's just my opinion. And I'm no musician.
