That is one of my favorite winter songs (not really a Christmas song though it gets played a lot when Christmas music is played) but only as long as it is the Johnny Mercer and Margaret Whiting version or the James Taylor and Natalie Cole version. Any other duet that attempts this song falls miserably short.
I heard a darn good version by Dr. John and Maria Muldaur - but I don’t think they recorded it. It was on the old Nashville Now show.
