Could it be "Welcome To The Jungle" by Guns N' Roses? They played that at about that time in the 4th quarter. Not sure. It begins with guitar, then the drums and bass come in. They often play it just before the opening tipoff, but they did play it late in the 4th last nite.
EDIT: sorry, I missed that in the original post; NOT "Welcome To The Jungle". Oops! I should pay attention before answering!
I think they did Aerosmith's "Sweet Emotion" late in the 4th last night also. I'm trying to remember.
