I hope you put up a recording of your show!
Also, it's hard to get high school marching bands (At least in Arizona) to play video game music. I saw one band last year do FF6 but for the most part the judges like that artsy crap. The bands who know they don't stand a chance are the ones who play the fun stuff.
EDIT: Also, I just realized I have the AU recording of "Hey Baby!" Great sounding band! My high school marching band played it too but didn't sound as good.
