I immediately fell in love with this Pastorale the first time I played it through. There are a couple of other lovely uploads on CB (Which I have linked in the Haynes Playlist) that are worst listening to.
Not quite a Christmas piece, but the Pastorale theme is fitting ;)
Walter Battison Haynes (21 November 1859 – 16 February 1900) was an English pianist, organist and composer. Although he died at a young age, his influence on the development of the English Victorian organ style was significant. He made the pilgrimage to Leipzig and on his return became a Professor of Harmony and Composition at the Royal Academy of Music. He was highly sought after as a teacher, and two of his best known students were Charles Macpherson and Harry Farjeon.
I found this score in a lovely publication by Barenreiter:
Sonntagsorgel, Volume II
