Accordng to Wikipedia: The "Huron Carol" (or "'Twas in the Moon of Wintertime") is a Canadian Christmas hymn (Canada's oldest Christmas song), written in 1643 by Jean de Brébeuf, a Jesuit missionary at Sainte-Marie among the Hurons in Canada. Brébeuf wrote the lyrics in the native language of the Huron/Wendat people; the song's original Huron title is "Jesous Ahatonhia" ("Jesus, he is born"). The song's melody is a traditional French folk song, "Une Jeune Pucelle" ("A Young Maid").
This uses all my Kobliczek recorders: the G alto (twice), tenor (twice), and the soprano in the last line. The bass is a plastic Yamaha, and the harp is sampled.
The score is on the Werner Icking archive.
The idea for doing this song came from Scott Lake, who asked me to provide some recorders for his version. The bass is played by his friend Andy McRory.
