Just wish the narrator had all his facts straight...during the Way of 1812, we were the American States, not the American colonies. It was Fort McHenry, not Fort Henry. Only 4 Americans died in the bombardment, not the piles of bodies referenced holding up the flag pole.
That's a great version, despite a couple of errors, and to be honest, most people don't have any idea what a "rampart" is.
At sporting events, I much prefer a basic rendition, with not so much focus on the singer.
