I love the song Tusk by Fleetwood Mac. And I'm fascinated by its becoming a marching band standard - especially for the USC Trojan marching band, which makes sense since they participated in the original recording of the song. Although it's freaky to think that the kids performing the song now were not even born when the original Tusk was recorded.
There are a bunch of Tusk videos online, and this one I think is particularly compelling, because it's right in the middle of everything. I don't think the herky-jerky look was intentional, just bad recording and/or editing, but I think it actually gives it a kind of neat style, almost like a strobe light in broad daylight - it makes the cheerleaders' movements a little surreal.
Turns out the real lyrics to the song are "UCLA sucks."
