R: You better watch out
   you better not cry
   you 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 knows when you are sleeping
He knows when you're awake
He knows when you've been bad or good
So be good for goodness sake

R: You better watch out...
