Years ago, "Mad" magazine published "Carols For Other Holidays":

Wreck The Walls
(For Halloween)

Wreck the walls and fences, golly!
Falalala Lalalala
Isn't Trick-or-treating jolly?
Fa (etc.)

Ring that doorbell, slash that tire,
Fa...
Trip the old man with a wire.
Fa.

Dressed in sheets and odd appareal,
Fa...
Can't tell John from Max or Carol,
Fa...

Which is good 'cause no one else can
Fa...
Just like grown-ups play Ku Klux Klan.
Fa...
