Santa Claus Is Coming To Town 
You better watch out 
You better not cry 
Better not pout

Santa Claus is coming to town 
He's making a list
And checking it twice; 
Gonna find out Who's naughty and nice

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! 
O! You better watch out! 
You better not cry
Better not pout
I'm telling you why
Santa Claus is coming to town
