The song I Saw Mommy Kissing Santa Claus is performed by John Mellencamp .
I Saw Momma Kissin ol'
Santa Claus
underneath the mistletoe last night
and she did not hear me creep
down the stairs to have a peek
why she thought that i was tucked up
in my bedroom fast asleep
well let me tell you that
i saw momma tickle ol'santa claus
underneath his beard so snowy white
and what a laught it would have been
if my daddy would have walked right in
i saw momma kissin santa claus last night
I Saw Momma Kissin Santa Claus
underneath the mistletoe last night
and she did not see me creep
down the stairs to take a peek
sure she thought that i was tucked up
in my bedroom fast asleep
well let me tell you that
i saw momma tickle ol'santa claus
underneath his beard so snowy white
and what a laught it would have been
if ol daddy have just walked in
i saw momma kissin santa claus last night
