Up on the house top reindeers paused
Out jumps good old Santa Claus
Down through the chimney with lots of toys
All part of a little ones with Christmas joys

Ho ho ho, who wouldn’t go? Ho ho ho, who wouldn’t go?
Up on the housetop,
Click click click
Down through the chimney with the good St. Nick

First come the stop in the middle bell
Hope dear Santa feeling well
Give her a doll that laughs and cries
One that will open and shut her eyes

Ho ho ho, who wouldn’t go?
Ho ho ho, who wouldn’t go?
Up on the house top, click click click
Down through the chimney with good St. Nick

Look through the stop in the middle bell
Hope just sees what a glorious well
Here’s a little hammer and lots of tacks
A whistle and a ball and wood *clap clap*
Ho ho ho who would’t go?
Ho ho ho who wouldn’t go?
Up on the house top, click click click
Down through the chimney with good St. Nick
Ho oh ho who wouldn’t go?
Ho ho ho who wouldn’t go?
Up on the house top, click click click
Down through the chimney with good St. Nick
