A college or high-school marching band typically plays raucous, low-brow music. But there is no reason why this has to be. For a more highbrow half-time entertainment at you football games, switch from pop music to Gregorian chant. In fact, Gregorian notation even looks like the half-time peformers on a football field: http://www.lphrc.org/Chant/ Instead of drunken louts coming to your football games, you will attract a clientele of medieval music lovers, eager to follow the Marching Monks of Minnesota. 

Dr. J. may have to defer to Professor Mondo, our favorite Medievalist on this one. While Dr. J. would certainly find entertainment in a Medieval marching band, he doesn’t think this will prevent drunken revelry at football games. Please recall that Belgian Monks refined and nigh-perfected the brewing of beer, and a Italians invented the pretzel. Indeed the while it is believed that the pretzel was designed to represent the holy trinity, it was actually modeled after the head of one of The Czar’s axes. The concave blade makes for good beheadings and the hollow spaces increase his speed factor. Dr. J. hopes this makes things clear.
