I tried a whole lot of French carols last year, and they were fine (Naxos has a couple of Quebec choir albums of Quebecois and French carols that are quite good). They are worth exploring. If I could find a good Spanish selection for this year, I would be thrilled. Anyone?
Going back a bit, Joni Mitchell's version of "Urge for Going" is on her recent "Hits" Collection (complementing her "Misses" compilation. I always like "River" as a Christmas song.
