"Illinois Loyalty" is the main school song of the University of Illinois. First performed March 3, 1906, 'Illinois Loyalty' is one of the oldest songs of its kind in the United States. The song was written by Thacher Guild specifically for the Marching Illini. Due to the song's length (over a minute long), it is normally played only at the beginning, halftime, and end of a game. However, it is not considered rousing enough for a large crowd at a game. For that reason, Oskee Wow-Wow was written five years later as the school's fight song.
