Amy Winehouse I saw Mummy Kissing Santa Claus Lyrics

I saw mommy kissing Santa Claus
Underneath the mistletoe last night
She didn't see me creep
Down the stairs to have a peep
She thought that I was tucked up
In my bedroom, fast asleep

Then I saw mommy tickle Santa Claus
Underneath his beard so snowy white
Oh, what a laugh it would have been
If daddy had only seen
Mommy kissing Santa Claus last night
