As determined by USA Today's College Football Fan Index, the University of Tennessee's "Rocky Top" is the No. 1 college football fight song.
Recorded in 1967 by the Osborne Brothers, the song immediately became a Top 40 hit before it made its way to Neyland Stadium.
Interestingly, "Rocky Top" is not actually the official fight song of Tennessee. However, when the university's Pride of the Southland Band played it during halftime of the 1972 Tennessee-Alabama game, the fans loved it. The reaction from the crowd inspired the band director to keep the song in the music book.
From then on, Vol fans turned to the song to uplift them after a loss or celebrate a win. "Rocky Top" even became an official state song of Tennessee in 1982. Now, it's nearly impossible to disassociate the song from the football team or any other University of Tennessee sport.
Georgia Tech, the University of Michigan, Notre Dame and Texas A&M among others also made the list, and it can be found here.
