This large gothic window located in the nave below the pulpit shows St. Cecilia, the patron saint of church musicians as an angel holding a harp, with flowers all around the feet. The inscription at the top reads "IHS, Let every thing that hath breath praise the Lord" and at the bottom: "To the Glory of God and in Loving Memory of William Irvine Johnston, Born Sept. 11th 1872 - Died May 28th 1943, Erected by Past and Present Members of the Choir." Mr. Johnston was choir leader from 1919 until his death.
