A "flashmob" by the Kentucky State Choir during opening ceremonies of the Olympics.
edit to add: Amazing. And take the time to think about the lyrics. Imagine yourself an American prisoner of war locked in the hold of a British warship, asking the men above if they can still see the American flag flying over their camp... and because its night... only as the rockets explode over the camp can the men above see the American flag still flies through the night.
The following verses rarely sung are come morning... when the sun rises, they now see the flag is still being held aloft, though crooked, by the bodies of all the Americans who gave their life to ensure it stayed flying high while the British targeted it all night trying to knock it down; that they gave their lives so that symbol of freedom would still be standing there come morning.
A national anthem written at a time when Americans were still proud to be American.
