Boy, this has come a long way since I checked in last winter. I think "Guest" has nailed it down pretty good, and many thanks to Cajun Angel, whose memories and experiences were worth more than all our speculations put together! A couple comments/questions:

--according to an online Cajun glossary I checked, "o fais dodo" should be "a fais dodo."

--Is it "Papa Noel will ring the bells" or "Papa Noel will bring the belles"?

--The more I listen to the lyrics the more I think Cajun Angel's "Aunt Tout Douce" is the better transcription, followed by "Auntie Douce."
