Don't know how it works now, but at least a few years ago game day ops would tell us what timeouts we could play. The "Mighty Taco" spirit timeout (now Tully's) would always be fight song, let's go Buffalo, cowbell. Now it appears that they added our fourth spirit song, the wobble, to the mix. Otherwise we could play whatever was next on the list, unless it was an opposing coach's timeout, which would be fight song only.
