The "LSU Alma Mater" was written in 1929 by Lloyd Funchess and Harris Downey, two students who developed the original song and music because LSU's first alma mater was sung to the tune of "Far Above Cayuga's Waters" and was used by Cornell University.  The band plays the "Alma Mater" during pregame and at the end of each home football game.  Also, members of the band join arm-in-arm at the end of rehearsals on Saturday game days and sing the "Alma Mater" before leaving the practice facility.

The network broadcasts a variety of local college and minor league sports broadcasts and is the de facto successor to the Buffalo-based Empire Sports Network.

The "Alma Mater" is the official school song of Dartmouth College, an Ivy League university located in Hanover, New Hampshire, United States.  Composed by Harry Wellman, class of 1907, it was officially adopted by the College in 1926.  The difficult to sing "Dartmouth Undying" replaced it in the fall of 1972, but the Alma Mater was restored as the official song in early 1973.  Richard Hovey of the class of 1885 wrote the original lyrics in 1894, titling the song "Men of Dartmouth".  Traditionally the original second verse was only sung during time of war.  On May 28, 1988, Dartmouth changed the title and words to reflect the presence of women as part of the College, since Dartmouth had become coeducational in 1972.  Nicole Sakowitz, Dartmouth Glee Club President was the first person to conduct the new Alma Mater.
