Last night Luke Bryan was on The Tonight Show with Jimmy Fallon, and he talked about his experience singing the National Anthem at the Super Bowl! From friends trying to get him to come out for drinks to other country artists trying to see how long the anthem is going to be for them to bet on it. Luke says to this day he is still shaking from the performance.
The part where he talks about the Super Bowl starts at 2:15 of the video.
