Carrie Underwood, one of the top country singers in the United States, performed at the Super Bowl Sunday. She spread joy and pride to everyone by honoring America by singing the National Anthem. While she sang, soldiers in Afghanistan, standing at attention were displayed on the big screens showing their respect to their country and the National Anthem. Carrie Underwood without a doubt rocked the stadium with her outstanding voice, and amazing talent. Good Job Carrie..
