This is just the chords with the two main riffs incorporated for when you're playing 
solo acoustic or something, thought it sounded pretty good.

First riff:
E---------------0- | 
B--5--5/3--3-3--1- | 
G--7--7/5--4-5--2- | 
D---------------2- | 
A---------------0- | 
E----------------- | 

Second riff, when the D chord is about to transition back to Amin:
E--3-3-2-0-2--0-- | 
B--3-3-3-2-3--1-- | 
G--2-2-2-3-2--2-- | 
D--0-0-0-0-0--2-- | 
A-------------0-- | 
E---------------- | 

simple enough. Chords:

Am
I'm not sure if there's a point to the story
             C             G
but I'm going to tell it again
Am
So many other people try to tell the tale
       C                   G
not one of them knows the end

         Am
It was a junk-house in South Carolina
       C       G
Held a boy the age of ten
Am
Along with his Older brother Billy
      C          G   Am
And a mother and her boyfriend
          D
Who was a triple loser with some blue tattoos
D
That were given to him when he was young
      Am
And a drunk temper that was easy to lose
              C        G         Em  Am
And thank god he didn't own a gun




(same progression through the next verse, but at the end it goes:)
Am      C  G Em      G      F     Am
Then during the break:
Am      G   F




(The next verse is the same chords. After the next break, it goes:)
Am
Billy broke in and saw the blood on the floor, and
Am
He turned around and put the lock on the door
Dm
He looked dead into the boyfriend's eye
    E
His mother was a ghost, too upset to cry, then




Those 4 chords repeat until the end where it returns to the Am C G format.
Simple enough. Enjoy!
