The tradition of playing and singing O Come All Ye Faithful as the closing hymn of Christmas in Christ Chapel is a favored tradition among Gusties. An arrangement specifically for Gustavus Adolphus College for Christmas in Christ Chapel was commissioned in 1976 and is performed each year. This is a picture of the performance from 1976.
I love O Come All Ye Faithful for this very reason! I reminds me of CinCC 🙂
