Christmas is coming, the goose is getting fat!
Please to put a penny in an old man's hat.
If you haven't got a penny, a ha'penny will do.
If you haven't got a ha'penny, God bless you.
(Sung as a round, the second voices starting when the first voices reach the second line)
Singing Together, Autumn 1984, BBC Publications
No source given, but the melody is a version of 'English Country Garden'.
