Lyrics:

So, you better watch out, you better not cry
Better not pout, I'm telling you why
Santa Claus is coming to town
He's making a list (and checking it twice)
Gonna find out who's naughty or nice
Santa Claus is coming to town
He sees you when you're sleeping
He knows when you're awake
He knows if you've been bad or good
So be good for goodness sake
You better watch out (better watch out), you better not cry (better not cry)
You better not pout, I'm telling you why
Santa Claus is coming to town
