I noticed that the other chords posted for this song all started on 'G' which is slid up 
from how it is played on the cd.
Here's is how it is played on the cd.
I know the riffs aren't 100% correct but it will work pretty well.

Verse 1:

F#      Ebm           B
  Yesterday I went outside
         C#           F#
With my momma's mason jar
         Ebm          B    RIFF 1 (Or play C#)
Caught a lovely Butterfly
F#      Ebm        B
  When I woke up today
          C#          F#
Looked in on my fairy pet
        Ebm         B  RIFF 2(then back to B for a moment before going to C)
She had withered all away
                      C#
No more sighing in her breast

Chorus:
                    F#
I'm sorry for what I did
     Ebm          B
I did what my body told me to
 C#                    F#
I didn't mean to do you harm
      F#7           B   RIFF 3           C#
Everytime I pin down what I think I want
        F#         Ebm          B
It slips away - the ghost slips aw- aaay


Verse 2 (same chords as verse 1):

I smell you on my hand for days
I can't wash away your scent
If I'm a dog then you're a bitch
I guess you're as real as me
Maybe I can live with that
Maybe I need fantasies
A life of chasing butterfly


Chorus:
                    F#
I'm sorry for what I did
     Ebm          B
I did what my body told me to
 C#                    F#
I didn't mean to do you harm
      F#7           B              C#
Everytime I pin down what I think I want
        F#         Ebm         B
It slips away - the ghost slips aw-aaay


(Stay on B)


Verse 3 (pretty much the same but slower):

F#      Ebm           B
  I told you I would return
        C#              F#
When the robin makes his nest
           Ebm          B  RIFF 1 (Or play C#)
But I ain't never coming back

F#

F#
I'm sorry
Ebm
I'm sorry
B                 F#
I'm sorry
