I'm glad Tim called attention to the new songbook from Nowell Sing We Clear. If you go farther into the "Nowell" Website, you'll find lyrics and background information for all the songs they recorded. You'll find similar information in a slightly different format at http://www.goldenhindmusic.com/, which publishes the music of John Roberts and Tony Barrand.

The most extensive online source of Christmas music that I've found is https://www.hymnsandcarolsofchristmas.com/ - a very interesting Website to explore.
