"Christmas Is Coming" is a nursery rhyme and Christmas carol (frequently sung as a round) with lyrics as follows:

Christmas is coming, the geese are 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!

 
Harry Belafonte sings an old English Christmas song: Christmas is Coming
