This is how I play it; all barre chords, each strummed once, save the verse "I'm a 
of fright..." in which each chord is strummed twice.
Another tab is on this site for the intro, but I also play that differently, so I'm 
that here as well.

          Bm           Bmmaj7         Bm7         A
There are few who would deny at what I do I am the best
       G           F#       G   A   Bm
For my talents are renowned far and wide.
        Bm         Bmmaj7         Bm6     A
When it comes to surprises in the moonlit night
  G             F#   G    Bm
I accel without ever even trying.
         Bm               Bmmaj7       Bm7       A
With the slightest little effort of my ghostlike charm
     G          F#       G   Am Bm
I've seen grown men give out a shriek
       Bm         Bmmaj7     Bm7         A
With a wave of my hand and a well placed moan
       G         F#           G   Am    Bm
I have swept the very bravest off their feet.
    G          F#             G        F#
Yet year after year, it's the same old cheer
      G       F#           Em       A7
And I grow so weary of the sound of screams
    Bm  Bmmaj7    A    G   F#
And I,  Jack, the Pump-kin King
     G        F#           G       F#
Have grown so tired of the same old thing
    Bm        Bmmaj7 Bm7             A
Oh, somewhere deep   inside of these bones
   G   F#    Em       F#
An emptiness began to grow
        Bm        Bmmaj7     Bm7         A
There's something out there, far from my home
  G       F#        F#    Bm2
A longing that I've never known
      Bm        Bmmaj7        Bm7      A
I'm a master of fright, and a demon of light
         G               F#  G  Am   Bm
And I'll scare you right out of your pants
     Bm     Bmmaj7        Bm7    A
To a guy in Kentucky, I'm Mister Unlucky
        G                F#      G   Bm
And I'm known throughout England and France
    Bm         Bmmaj7      Bm7         A
And since I am dead, I can take off my head
   G      F#    G    Am   Bm
To recite Shakespearean quotations
   Bm         Bmmaj7  Bm7           A
No animal nor man can scream like I can
         G          F# G  Bm
With the fury of my recitations

G       F#         G         F#
But who here would ever understand
         G       F#            Em       A7
That the Pumpkin King with the skeleton grin
      Bm   Bmmaj7    A              A    G    F#
Would tire of    his crown, if they only understood
     G           F#       G    F#
He'd give it all up if he only could
    Bm         Bmmaj7 Bm7         A
Oh, there's an empty  place in my bones
     G         F#      Em    A
That calls out for something unknown
    Bm       Bmmaj7      Bm7        A
The fame and praise come year after year
     G       F#        F#7   Bm2
Does nothing for these empty tears
