For those who have tired of "What Does the Fox Say?", good news. You only have to put up with it for another home game. Every season the Gopher Football game production grabs onto what most would consider a dumb, novelty type song. Two years ago it was "Party Rock Anthem" by LMFAO. Last year it was "Gangnam Style". This year we have the Fox. Next year it'll be something else. If the students like it, then so be it.
As for "Sweet Caroline", if the fans get up and sing and have fun, then it should long continue. The lack of atmosphere and people sitting on their hands has long been a complaint of many. Since we have a song that people get into, there's no reason to stop. So what if Badgers fans think it's their song. Sing alongs to this tune predate Camp Randall in stadiums and in bars and parties in general. For anyone to think otherwise is absurdly delusional. This isn't like the time they played "Jump Around" against Wisconsin at the Dome, a move that almost had me ready to rush the control booth in anger. I'm not a Neil Diamond fan in the slightest, but the appeal of "Sweet Caroline" is impossible to deny.
As for the idea of the song getting played as a dig at Penn State over the scandal, I'd buy that the fan who voted for it potentially had that in mind as an in joke. However, the folks in the U of M athletic department and game production staff come off as generally unaware enough that the reference was likely neither intentional or even noticed on their part. Had someone caught it, I think they might have skipped the tune in order to not possibly insult the visiting Penn State dignitaries.
