This year saw the installation of a new pipe organ, the Casavant Opus 3867, an anonymous gift to the congregation. This organ contains elements of every organ that has served this church. The base of the reredos woodwork is preserved from the original 1903 Lyon and Healy organ. The upper portion of the reredos came with the gothic architectural embellishments that were done in 1934. The new organ, out of its twenty-nine ranks (sets of pipes), contains seven ranks from the previous 1958 Wicks organ.
