The verses are all just a drubbing E chord; you can hammer on the 4th and 5th strings of the chord and let the low E ring to add some character.

The chorus uses an A chord with a walk down in the bass line. Focus your strum to nail the bass notes and just catch the rest of the chord.

E
I was drunk, I was down
Wondering around my bed
I was drunk, I was down
Wondering around my bed
E A* x2
I called out your name
E
I called out your name
I was bleeding, I was exhausted
I was suffering from the altitude
Picked up your sin and lost it
And I suffered from your attitude
Called out your name
I called out your name
I called out your name
Called out your name
I was summoned by the angels
That be hung beside your picture
Not allowed to feel to the touch
To hold forever in prison along
I called out your name
Called out your name
Called out your name
Called out your name
I was drunk, I was down
I was wondering around my bed
I was drunk, I was down
I was wondering around my bed
I called out your name
I called out your name
I called out your name
I called out your name
