Wisconsin has an alma mater too:
"Varsity"
Varsity, varsity
U rah rah, Wisconsin
Praise to thee we sing (we sing!)
Praise to thee, our alma mater
U rah rah, Wisconsin
It's played at the halftime of every game, and if we win, it's played once or twice more during Fifth Quarter (the time after the game where the band plays a million songs and all the students sing and dance in the bleachers). Everyone puts their arms around the person on either side of them and sways back and forth as they sing . . . then for the last "U rah rah Wisconsin" you "wave goodbye." It's really cool to see an entire stadium full of people with their arms around each other swaying back and forth.
Here's a website on Wisconsin's school songs:

According to it, "On Wisconsin" has been adopted by 2,500 schools and colleges as their fight song!
