this is kinda my acoustic version for this awesome song.
I changed the riff cos the original version is in dropped-c and I put this in standard tuning.
you can also use power chords for it or whatever...enjoy!

Intro

D|----------------------------|----------------------------|
A|-1-3--3--3-1-3--3--3-1-3--3-|-6-3--3--3-1-3--3--3-1-3----|  2x
E|----------------------------|----------------------------|

Am                       G
You my friend / You're a lot like them
       Em                       F
But I caught your lie / And you know I did
         Am                   G
Now I'm lost in you / Like I always do
        Em                       F
And I'd die to win / 'Cause I'm born to lose

[Chorus:]
 C                   G
Firefly / Could you shine your light
       F                               G#5 (6x)       A#5 (2x)
Now I know your ways / 'cause they're just like mine
         C                 G
Now I'm justified / As I fall in line
          F                        G#5 (6x)
And it's hard to try / When you're open wide

Intro (1x) then Am

Am                      G
Take my hand / We'll be off and then
            Em                 F
We'll come back again / To a different land
       Am                     G
Now I like this way / You can go away
        Em                     F
If you guess the name / You cannot replace

[Chorus]

 Am
Bring me your enemies
 F
Lay them before me
     Am  G  F     Am  G  F     
Am  G  F
And walk away /  walk away /  WALK AWAY!!!

[Chorus]

Fuck you firefly
Have you lost your light
Now I hate your ways
'cause they're just like mine
So you lost my friend
Such a sorry end
And I don't know why
So I choke and smile

Intro (2x)
