The main part is G F Eb F G. I'm not sure what positions he is playing on the album.
You could do it pretty easily if you dropped down a half step and played E-shape
bar chords. I'm tabbing it out with normal tuning and playing A-shape power
chords, simply because it's easier (and might actually be right).

Main part: G* F Eb F G

Intro: (Main part twice)

(Main part - Played once for each two lines below)
I know you never asked for my opinion
But I'd say that horse is crazy
I know what I think doesn't matter any more
But I'd say his mind is gone
And I know you know what I know
Even though you'd rather die than say it
I know you feel the same way
Or you wouldn't be sleeping on the lawn

G           C
I heard the hooves crack the window
Saw the body come through
        G
Saw the big brown eyes flashing
I fell all over you
      D                C       G
I got pressure bearing down on me

(Main part - Played once for each two lines below)
There was a reason why I came here
But I guess now it doesn't matter
I had a good, good, good, good reason
But I guess now you couldn't care
There is a certain kind of feeling that you get
When you're totally helpless
And there's a different world waiting for me
When I lift my head up from your thick, dark hair

G           C 
I heard the hooves crack the window
Saw the body come through
        D
Saw the big nostrils flaring
I fell all over you
      D                C    G
I got pressure bearing down on me

G           C
I heard the hooves crack the window
Saw the body come through
        D
Saw the big brown eyes flashing
I fell all over you
      D                       G
I got pressure bearing down on me

Outro: (Main part four times)
