And I would cover the 4 years before that. So either he's lying or he got some bad information.
Either way, this is a minor point in what was already a dumb argument. The band's not going to change and if the dumb, harmless stuff they do is enough to ruin the game for you, you need to get the **** over yourself. Don't like the chants? Be loud, encourage the people around you to do the same, and drown them out. Don't like it that they're trying to get cowbell to catch on at the basketball game? Stop being so damn self-concious and go nuts during more than one song (Sandstorm) during the game, so the AD/arena people aren't looking for new ways to get you to participate. It's an easy fix, but unfortunately it requires a little more effort than writing a bitchy forum post.
