Originally by Florence + The Machine but I really love this version of the song so here it goes:

Capo 5

N.C.
Regrets collect like old friends
Here to relive your darkest moments
I can see no way, I can see no way
And all of the ghouls come out to play

Am        F                        C
And every demon wants his pound of flesh
              G                     Am
But I like to keep some things to myself
          F              Dm 
I like to keep my issues drawn
            F                  C
It's always darkest before the dawn

C
And I've been fool and I've been blind
                             F
I can never leave the past behind

I can see no way, I can see no way
C
I'm always dragging that horse around

Am          F                        C
Our love is pastured such a mournful sound
                  G                      Am
Tonight I'm gonna bury that horse in the ground
          F              Dm 
I like to keep my issues drawn
                F                  C
But it's always darkest before the dawn

C
Shake it out, shake it out
Shake it out, shake it out, oh whoa
C
Shake it out, shake it out
Shake it out, shake it out, oh whoa

F
And it's hard to dance with a devil on your back
             C
So shake him off, oh whoa

Am       F                      C
And I am done with my graceless heart
                     G                      Am
So tonight I'm gonna cut it out and then restart
                 F              Dm 
'Cause I like to keep my issues drawn
            F                  C
It's always darkest before the dawn

C
Shake it out, shake it out
Shake it out, shake it out, oh whoa
C
Shake it out, shake it out
Shake it out, shake it out, oh whoa

F
And it's hard to dance with a devil on your back
             C
So shake him off, oh whoa

Am                              F
And it's hard to dance with the devil on your back
C                                  G
And given half the chance, would I take any of it back
Am                           F
It's a fine romance but it's left me so undone
Dm          F                  C
It's always darkest before the dawn

Dm
And I'm damned if I do and I'm damned if I don't
Am                                      G
So here's to drinks in the dark, at the end of my road
Dm
And I'm ready to suffer and I'm ready to hope
Am                            G
It's a shot in the dark aimed right at my throat
       F
'Cause looking for heaven, found the devil in me
Am                            G
Looking for heaven, found the devil in me
    F                                         G
But what the hell, I'm gonna let it happen to me, yeah

C
Shake it out, shake it out
Shake it out, shake it out, oh whoa
C
Shake it out, shake it out
Shake it out, shake it out, oh whoa

F
And it's hard to dance with a devil on your back
              C
So shake him off, oh whoa

C
Shake it out, shake it out
Shake it out, shake it out, oh whoa
C
Shake it out, shake it out
Shake it out, shake it out, oh whoa

F
And it's hard to dance with a devil on your back
             C
So shake him off, oh whoa

C
Shake it out, shake it out
Shake it out, shake it out, oh whoa
C
Shake it out, shake it out
Shake it out, shake it out, oh whoa

F
And it's hard to dance with a devil on your back
             C
So shake him off, oh whoa
