[Verse 1]
Am              E
A letter once a year
   Abm     C#m          A
To let you know whether I've been good
Am                  E
And all the kids at school
     Abm        C#m         A
Said you're not real, but I knew the truth
Am                    B7
Nobody, nobody, nobody else
 
[Chorus]
N.C
Only Santa knows
E    C#m    F#m7
When you're asleep
B
Only Santa knows
E    C#m         F#m7
What cookies you leave
B
Only Santa knows
E      C#m       F#m
If you really do believe
B
Only Santa knows
Am                E
Ooooh Ooooh Ooooh Ooooh
 
[Verse 1]
Am                  E
I saw you cross the moon
  Abm    C#m       A
I ran inside to go straight to bed
Am                  E
In the magic of the night
  Abm      C#m                A
I close my eyes and watch reindeers fly
Am                    B7
Nobody, nobody, nobody else
 
[Chorus]
N.C
Only Santa knows
E    C#m    F#m7
When you're asleep
B
Only Santa knows
E    C#m         F#m7
What cookies you leave
B
Only Santa knows
E      C#m       F#m
If you really do believe
B
Only Santa knows
Am                E
Ooooh Ooooh Ooooh Ooooh
 
[Bridge]
F#m                         B
I can't wait 'til Christmas morning, before the day's begun
F#m                              B
I'll check the garden to see if all of the carrots are gone
E                               A
Tell mom and dad that we've got presents
      B
Underneath the tree
              C#
We'll have to wait and see
 
[Chorus]
N.C
'Cause only Santa knows
F#   Ebm    Abm7
When you're asleep
C#
Only Santa knows
F#   Ebm    Abm7
What cookies you leave
C#
Only Santa knows
F#     Ebm       Abm7
If you really do believe
C#         Bm      D
Only Santa knows
           Bm      D
Only Santa knows
           E F#
Only Santa knows
