There's really only one sane answer here...I'd PREFER the students not do it, because it's meant the banning of some fun, and in the case of Tiger Rag, traditional music from Tiger Stadium. At the same time, I'm sensible enough to know that the minute you tell a group (any group, but it makes it even worse when they're young and drunk) that they absolutely CAN'T do something they'll be sure to do it even more.
Put another way, since there's absolutely no way the university can enforce this (can't run up and start kicking out students who are all chanting something) the more people continue to make a giant deal out of it the more it will exacerbate the problem and push the students to keep it up. I'm frankly surprised no one has decided to make the chant fir Pre-game!
1- This is not an endorsement of the chant...see the first sentence above.
2- I am 42 and have two boys, both of whom made appearances at TS this season. Neither had any clue what was being said, and we sit directly across from the students in EU 631.
