The problem, as I see it, is most singers don't love the song or have an appreciation to what that song stands for. For some of us, that song done PROPERLY, can and will bring a tear to your eyes. The hype of the game, the crowd, and the magnitude of the viewing audience have too much influence on the singer. The real influence should come from love of country and the respect being given to those who have given so much to afford us the freedom and justice refered to in the song.
