You better watch out
  You better not cry
  You better not pout
  I'm tellin' you why
  Santa Claus is comin' to town
  
  He's makin' a list
  Checkin' it twice
  Gonna find out who's naughty or nice
  Santa Claus is comin' to town
  
  He sees you when you're sleepin'
  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
  You better not cry
  You better not pout
  I'm tellin' you why
  Santa Claus is comin' to town...to town --
  
  Over there
  Santa Claus is comin' so be prepared
  Don't you cry or worry go and get your stocking hung
  Every little thing to do is done
  Santa's list of toys is gone the tree the cue
  And don't forget to brush
  Every little one
  'Cause soon as your sleepin'
  Teeth police will come checkin' to see if every pearl is glistenin'
  Don't be missin' any spot or they'll tattle-tale ans Santa he won't come
  
  You're dealin' with toyland springs
  When he brings the season joy with toys and things
  But if you go dancin' Samba through the night
  Be warned, beware
  Or else you'll scare the hair off of Rudolph and he'll fly from here
  That's a fact and then you'll cry and rave and wish that you'd behaved
  So heed this warning before morning comes upon you
  Go to sleep and goodnight!

  All the boys and girls dream of Toyland,
  Wish that the snowman soon would play
  And they are sure to get their wishes met
  When they hear the words we say...
  
  You better watch out
  You better not cry
  You better not pout
  I'm tellin' you why
  Santa Claus is comin'
  Santa Claus is comin'
  Santa Claus is comin' to town
  To town!
  To town!
  Look out old Santa is back - yeah!
