While shepherds watched their flocks by night

My husband bought me a "Garage Band" program ages ago, but I only recently figured out that it's possible to record voice tracks on the computer's native microphone, if a little tinnily.  I've spent many a happy hour this week laying down all four tracks of a series of Shape Note tunes, including this Christmas carol.

Even when it's just me singing with myself, it's surprising how hard it is to get all the voices to blend.  I'm going to be practicing for a long time laying down the tracks, trying to keep all the parts together and on the beat.  What could be more fun?  And I'll need a better microphone at some point.  But there are only 45 minutes of Christmas left, so this carol has to upload in its current state.
