As Fry says in the video--it's a LOCAL DERBY OF AMATEURS. With 70,000 fans. And two giant marching bands, which is part of what makes the pageantry work. Bands are INTEGRAL to college football. They aren't pasted on. They're part of the magic.
Also, the BYU drumline performance prior to the game (northwest corner concourse) is epic. You gotta check that out.
