This is sung as a "round", and there are no additional lyrics. BTW, forget about PP&M, if you want to hear an excellent version go get "The Last Month of the Year" by the Kingston Trio. Yes, that's right....they made the very best Christmas album yet- full of great traditional songs, and none of the typical "Chestnuts Roasting on the blah blah blah" junk that everyone seems to think represents Christmas.
