Singing The National Anthem/Star Spangled Banner

With the Super Bowl happening on Sunday, I wanted to sing The National Anthem/Star Spangled Banner, written by Francis Scott Key. I'm hoping to use this video for possible auditions to sing at Sports Events. My lofty goal is to sing at a Super Bowl. What are you doing that's a bit bigger than yourself? Would like to know. Thanks for your support. Blessings.
