This hits home to me. It's a rarity that we ever hear it in its true form. Whenever there's a gigantic sporting event, we "get" to hear a version that's.. well, not so much the intended version.
It should always be 1:50-2:10 long. It should be sang the way Francis Scott Key intended. And the singer should never try to outclass the song itself. And for goodness sake, get the words right!
