Day 19 is a tune that has been recorded by the likes of Harry Belafonte, Odetta and St. Olaf Choir "There's a Star in the east on Christmas morn. Rise up shepherd and follow".
Day 20 is Chirstmas Carol favorite, "Up on the house top reindeer paw..." :-) Anyone remember this version? I think this was the first time that Alvin was not in trouble!
