"Hail to Old O.S.U." is the song from which the fight song for Oregon State University is based. It was written by Harold A. Wilkins in 1914 and is played mainly at sporting events like football and basketball games. The lyrics have been slightly altered since being written "to conform to a changing culture", changing to conform to new initials (O.A.C. became O.S.C., and later, O.S.U.), and the use of a more gender-neutral version. The music and lyrics were copyrighted in 1914 and are now public domain.
