The original song is a semitone up from these chords, you could put a capo on the 
first fret if you like. I just worked out the chords in this key because it's easier to play.

   Em                  Am
It happened again last night
   Em               Am
It happened again alright
Em                Am      Em
Honey it makes me want to cry
    Am   D             
Too late I fell out of bed
Am                 Em
Hit the ceiling instead
            Bm
I'd turned into a butterfly

Em                    Am
God didn't spend much time
Em                 Am
This was a hit and run
Em                     Am  Em
Clearly the wings were oversized
   Am   D
In all, well nothing was right
Am                   Em
Still it was quite a sight
            Bm
I'd turned into a butterfly

         Am         Bm          Em       A
But the last time I looked in a mirror
   Am                 Bm          Em     A
It looked like it was going to be fine
        Am          Bm            Em     A
And the last time I looked in the mirror
    Am                Bm          Em
It looked like it was going to be fine

Instrumental part (sorry I couldnt work this out)

Em                Am
Baby I don't know why
Em                Am
I was the average guy
Em               Am    Em
And I was almost satisfied
   Am D 
To be just one in the crowd
Am                  Em
Not too tall or too loud
          Bm
I turned into a butterfly

Em               Am
Tired but always clean
Em                Am
Staying away from dreams
Em                 Am      Em        Am
So I lie sleepless by your side most nights
D
A twitch in my back
Am                 Em
Gently life would attack
           Bm
I'd turned into a butterfly

        Am          Bm          Em      A
But the last time I looked in a mirror
   Am                 Bm          Em    A
It looked like it was going to be fine
        Am          Bm            Em     A
And the last time I looked in the mirror
   Am                 Bm          Em
It looked like it was going to be fine

Am             Bm      Em        A
Once past the drowning panic
Am      Bm         Em        A
And the longing to fly
    Am     Bm         Em      A
Whatever I see in the mirror
    Am              Bm          Em
I'm sure that it's going to be fine
