The Symphonie-Passion by Marcel Dupre was performed following a lecture on various factors that influenced the development of the organ symphony in France. In addition to the lecture recital, three other public recitals were performed, including solo compositions for the organ and three chamber works for organ and instruments. The first solo recital, including works of J. S. Bach, P. Hindemith, L. Sowerby, and L. Vierne, was performed on June 4, 1969. On April 17, 1970 the second solo recital was performed. Compositions by J. S. Bach, D. Buxtehude, M. Duprd, N. Dello Joio, S. Karg--Elert, and J. Langlais were included in the program. On January 25, 1971, a program of organ chamber works by N. Lockwood, D. Pinkham, and F. Martin, as well as solo works by F. Lizst, W. Latham, and Marcel Duprl, was performed. The four programs were recorded on magnetic tape and are filed with the written version of the lecture as a part of the dissertation.

The lecture recital was given on November 20, 1979. The final movement of Widor's Symphonie Gothique, opus 70, the first movement of Widor's Symphonie Romane, opus 73, and the first movement of Dupré's Symphonie-Passion, opus 23 were performed following a lecture on Gregorian Chant in the organ symphonies of Widor and Dupré. The lecture included a brief historical discussion of the decline of organ literature following the French Classical School, the development of the Modern French Organ School beginning with the establishment of the organ department at the Paris Conservatory, the revival of plainsong and the establishment of the School of Solesmes, and the influence of César Franck and the organ symphony. The main body of the lecture included biographical sketches of Widor and Dupré, a discussion of the general characteristics of their organ symphonies, with the emphasis upon those movements specifically employing the use of Gregorian chant.
