See, now that's a song that'll get your blood up, that you can sing marching to battle. Unfortunately the lyrics aren't all that's needed in a national anthem. As a northerner, I'll reciprocate and say that "Bonnie Blue Flag" is pretty good, too.
I second that (e)motion! I've liked it since I saw the movie "The Horse Soldiers" as a kid (and that was in the 1980s).
I'm kinda partial to "Stonewall Jackson's Way" meself.
