Charles Tournemire was organist at the Basilica of Ste. Clotilde in Paris, where César Franck had been. L'Orgue Mystique is his grand collection of organ settings of propers of the church year, pieces based on themes taken from the chant melodies of the day. Quasimodo is name for the First Sunday after Easter, because the first word of the Introit for that Sunday is "Quasimodo." This part of L'Orgue Mystique is No. 18 of the Cycle de Pâques (Easter Cycle).
This is one of the numbers on a recital that Wayne Fisher played at St. Thomas Church in New York City on June 8, 1975. The organ is Aeolian-Skinner Op. 205-A, also identified in the Pipe Organ Database (Organ Historical Society) as Gilbert F. Adams (1969), its sound made famous by Marcel Dupré in his recordings of Widor and Franck and his own music.
Wayne Fisher (1910-1985) taught organ for many years at the Cincinnati College-Conservatory of Music of the University of Cincinnati, and served as chairman of the organ department.
