Lewis & Hitchcock installed new Great and Positiv divisions over the reredos (wall behind the altar) in 1970 and collected various ranks to form a Swell division behind the original Möller organ case. Over the next decade, the stop list was modestly expanded while the instrument’s tonal orientation was shifted away from its neo-baroque aesthetic.
In 1999, a new two-manual mechanical-action organ of 35 stops and 42 ranks was built by Orgues Létourneau Limitée of St-Hyacinthe, Québec. It incorporates several ranks from the previous organs after restoration and revoicing to fit the new French tonal aesthetic.
In 2022, the instrument was refurbished, including the replacement of two stops in the Récit division and a full revoicing of the division. The organ’s reed stops were also restored at the Létourneau workshop and tonally finished at Augustana. The design of the instrument allows the faithful rendition of both classic and symphonic repertoire, with the recent work highlighting the variety of colors available for accompaniment at all dynamic levels.
