They have two Christmas CDs out, and a concert DVD that includes a Christmas set. Great stuff! If you get a chance to see them in person, I highly recommend it. Check their concert schedule on their website. Each year they also have an 25-day countdown to Christmas online
. (I think this may be last year's---all the "windows" are clickable, but when the countdown is active, you can only click up to the current date.) Each day in December, you get a new interview, song, recipe, or something related to SNC. Enjoy!
