You'd better watch out, you'd better not cry;
You'd better not pout, I'm telling you why;
Santa Claus is coming to town.

He's checking his list, checking it twice;
Going to find out who's been naughty and nice.
Santa Claus is coming to town.

He knows who is sleeping, he knows who is awake.
He knows who has been bad or good;
So be good for goodness sake.

You'd better watch out, you'd better not cry;
You'd better not pout, I'm telling you why;
Santa Claus is coming to town.
