Arranged by Eric Kuhlstrom (ca. 1860s - 1940s). I know nothing about him other than the information presented on imslp when downloading his Christmas Album book for piano.
I recorded this with a few different settings but nothing really satisfied me. I suspect it is suited for the piano, or even harpsichord, a lot better than the organ (a 'lighter' and more 'playful' organ other than Caen would sound better I suspect). However, it is a nice little setting of this popular Christmas carol.
Hope you enjoy.
