"Christmas is coming, the goose is getting fat, Please put a penny in the old man's hat. If you haven't got a penny, a ha'penny will do. If you haven't got a ha'penny, then God bless you."
This seems to be rare in tradition, and yet *I* learned it that way, in a version still close to the British, since it mentions ha'pennies (which I first heard as "hay-pennies," which made no sense at all). So I'm filing it on the assumption it's going to be collected in tradition in the future, at least. - RBW
