According to John-Paul Buzard, the last curator for the organ, it played through about 1984, when continuing water damage and age made it impractical to do any more work on the organ. Coinciding with a major renovation of the auditorium, the organ was removed and dispersed. The 1949 Aeolian-Skinner console went to Buzard Op. 5 at St. James United Methodist Church, Danville, Illinois; the 16' Open Wood was capped and added to the 1965 Casavant in Smith Hall as the 32' Untersatz; the Pedal Trombone was lengthened and had new reeds fitted to become the half-length 32' Kontraposaune on the Casavant.

Clarification in a letter dated July 19, 2007, by John E. Sperling, Tonal Director Emeritus of Wicks. The Aeolian-Skinner console was retained as is. The Wicks works was to include all new chests and reservoirs, new relays, revoicing of all pipes (with a view to making them louder) and nine new ranks of pipes. Since the 1914 Choir pipes were in poor condition, they were replaced with pipes from Wicks stock. The organ was dispersed in the early 1980's when the Auditorium was renovated and renamed Foellinger Auditorium.
