Intro: A           F#m         E

A                  
Skeleton you are my friend
F#m                 E
But you are made of bone

(continues in a similar vein until the chorus)


Chorus: (chord changes are oddly timed here)

A
And I should have known
        F#m     E   D
That it wouldn't be long until you've
F#m      E           D       A
Got me standing in an awkward position with
F#            E           D       A
Unwanted attention and a need for explanation and it's
F#        E         D       A
Not that I'm letting go of you
F#        E         D       A
But I dunno what to do

...Verse again. Chorus again.

Bridge: (strum faster)

Dm
And some
Am
Times
Dm                  
At at at at at at at night

(and so on)

When it decelerates, start playing an A major chord instead, then slow down into the verse:

A
...And smash... 
A             F#         E
But skeleton, you are my friend...
(etc)


It's one more go at the chorus, and then the song finishes, which is all easy enough.
