Lyrics:

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

Puck:
He's making a list
And checking it twice;
Gonna find out Who's naughty or nice

Puck and Samuel's Character:
Santa Claus is coming to town
Santa Claus is coming to town
Santa Claus is coming to town,

Samuel's Character:
He sees you when you're sleeping
He knows when you're awake
He knows if you've been bad or good
You better be good for goodness sake!

Finn:
You better be good for goodness sake!

Puck:
O! You better watch out!
You better not cry

Finn:
You better not pout
I'm telling you why

Puck with Finn and Samuel's Character:
Santa Claus is coming to town
Santa Claus is coming to town
Santa Claus is coming to town (Finn:Ho Ho Ho Ho)

Samuel's Character:
He sees you when you're sleeping
He knows when you're awake
He knows if you've been bad or good
You better be good for goodness sake!

Finn:
You better be good for goodness sake!

Puck:
You better watch out!
You better not cry

Finn:
You better not pout
I'm telling you why

Puck with Finn and Samuel's Character:
Santa Claus is coming to town (Finn: Yeah)
Santa Claus is coming to town
Santa Claus is coming to
Santa Claus is coming to town
