There is a Michigan channel on YouTube that has highlights of this game. While the channel obviously has a bias toward Michigan, the highlights are "neutral" and actually show the good and the bad from both sides. When we score our first touchdown, Memorial Stadium is LOUD. There is actually a comment on the video that I remember (paraphrasing here) that said, "I have never heard 57k people be so loud."
I would agree that Memorial has not even gotten close to that since that game ... but it shows that the acoustics of our stadium allow for a VERY loud crowd with only 57k in attendance ... so we better be rockin' vs. PSU!!
