In Canada, the Philippines and the United States, the "Trio" section "Land of Hope and Glory" of March No. 1 is often known simply as "Pomp and Circumstance" or as "The Graduation March" and is played as the at virtually all high school and some college graduation ceremonies. It was first played at such a ceremony on 28 June 1905, at Yale University, where the Professor of Music Samuel Sanford had invited his friend Elgar to attend commencement and receive an honorary doctorate of music. Elgar accepted, and Sanford made certain he was the star of the proceedings, engaging the New Haven Symphony Orchestra, the College Choir, the Glee Club, the music faculty members, and New York musicians to perform two parts from Elgar's oratorio "The Light of Life" and, as the graduates and officials marched out, "Pomp and Circumstance" March No. 1. Elgar repaid the compliment by dedicating his "Introduction and Allegro" to Sanford later that year.
