Hello, Allison:

It's the opening (and title) song of John Roberts and Tony Barrand's Hail Smiling Morn, one of their "Nowell Sing We Clear" recordings, subtitled A Pageant of Mid-Winter Carols. We have it on our web site. Drop me a line via e-mail, and we can talk about it. I'm not tune-sending capable, I fear.
