Christmas Carol Spotlight: Pat-a-Pan

We Americans tend to be completely oblivious to the treasure of French Christmas Carols.  But there are a few we've likely come across a time or two, and the most prevalent of these is Pat-A-Pan. (Because of an English translation in the 18th century).  The song reminds me of a little bird, but it's supposed to remind you of a snare drum.  And I never resent being told to be merry.  I need reminders. (The version from Mindy Gledhill's new album is pretty great.)
