If you can't locate the twirlers themselves, check with those crazy drummers. I still get a surge of adrenaline listening to the Eagle Fight Song.
Music is a powerful motivator.
Actually, I played a sousaphone, the kind of tuba invented by Lieutenant Commander John Philip Sousa in 1892 especially for his Marine marching band. I mentioned that I learned about people as a tuba player. My experience taught me that rowdiness increases geometrically with one, the size of one's instrument and, two, the distance one sits away from the director's podium in the band hall. Thus, tuba players are a good deal rowdier than trumpet players, somewhat rowdier than trombone and baritone players, but not as out of control as those crazy drummers. I also learned something about organizations during my tuba playing days.
