The "Marines' Hymn" is the official hymn of the United States Marine Corps, introduced by the first Director of USMC Band, Francesco Maria Scala.  It is the oldest official song in the United States Armed Forces.  The "Marines' Hymn" is typically sung at the position of attention as a gesture of respect.  However, the third verse is also used as a toast during formal events, such as the birthday ball and other ceremonies.  Western Illinois University uses the hymn prior to all football games.  They are the only non-military academy allowed to use the hymn.  The university has had permission to use the official nickname, mascot, and hymn of the Corps since 1927.
