Whole song is just 3 chords, verse and chorus are the same. Bridge is slightly different. 

Em                Bm
Black, you are my enemy
    D/F#         Em
And I cannot get close to thee
                     Bm
Our life is ruled by enmity
    D/F#           Em
And I can't weaken that

Em                Bm
The only way that I can see
D/F#           Em
Is to hold you close to me
                     Bm
To love you for it's meant to be
  D/F#        Em
I weaken your attack

Everything was lucked and downy
What was good was up from under
Until black, that awful tender
Came and popped my sense of wonder

All at once all eyes turned at him
Leaving me an unwatched body
And it sagged, my body's rib cage
Out from under ogler's study

Black was decomposing quickly
This was found offensive to me
His disrespect for life's proprieties
Made me scared he would destroy me

Em                Bm
Black, you are my enemy
    D/F#         Em
And I cannot get close to thee
                     Bm
Our life is ruled by enmity
    D/F#           Em
And I can't weaken that

Em                Bm
The only way that I can see
D/F#           Em
Is to hold you close to me
                     Bm
To love you for it's meant to be
  D/F#        Em
I weaken your attack

So I thought I'd try to cut him
Try to force him 'neath my level
The only way to equal to him
Would be hit him with a shovel

But to really rise above him
That would be the final evil
So instead I asked the sucker
If he'd care to see my rooms

And as a friend and as a comrade
And all the things that these implied
I made him leave what it was that he had
Used to keep us unallied


Em                Bm
Black, you are my enemy
    D/F#         Em 
And I cannot get close to thee
                     Bm
Our life is ruled by enmity
    D/F#           Em
And I can't weaken that

Em                Bm
The only way that I can see
D/F#           Em
Is to hold you close to me
                     Bm
To love you for it's meant to be
  D/F#           Em
I weaken your attack 

BRIDGE:
Em              Bm
Now black and I we are together
Em          Bm
Fairly just inseparable
Em               Bm
And in the terriblest of weather
    D
Our bonds are incorruptible

CHORUS:
Em                Bm
Black, you are my enemy
    D/F#         Em 
And I cannot get close to thee
                     Bm
Our life is ruled by enmity
    D/F#           Em
And I can't weaken that

Em                Bm
The only way that I can see
D/F#           Em
Is to hold you close to me
                     Bm
To love you for it's meant to be
  D/F#           Em
I weaken your attack
