[Verse 1]

A letter once a year

To let you know whether I'd been good

And all the kids at school said you're not real

But I know the truth

Nobody, nobody, nobody else

[Chorus]

Only Santa knows when you're asleep

Only Santa knows what cookies you leave

Only Santa knows if you really do believe

Only Santa knows

[Verse 2]

I saw you cross the moon

I ran inside to go straight to bed

In the magic of the night (Magic of the night)

I close my eyes and watch reindeers fly

Nobody, nobody, nobody else

[Chorus]

Only Santa knows when you're asleep

Only Santa knows what cookies you leave

Only Santa knows if you really do believе

Only Santa knows

[Bridge]

I can't wait 'til Christmas morning before the day's bеgun

I'll check the garden to see if all of the carrots are gone

Tell mom and dad that we got presents

Underneath the tree, we'll have to wait and see

[Chorus]

'Cause only Santa knows when you're asleep

Only Santa knows what cookies you leave

Only Santa knows if you really do believe

Only Santa knows

[Refrain]

Only Santa knows

Only Santa knows

[Outro]

He's on the roof
