For those of you that have seen Brantley's video on youtube 
of him doing this classic Vern Godsin song, here's how he plays it.
For those of you that haven't, look it up cuz it's awesome


tune the guitar a half step down


You ran (D) right into the bedroom
I (G) ran off to the bar
(A) Another piece of heaven gone to (D) hell
The words you spoke in anger
(G) tore my world apart
(A) I sat there feelin sorry for my(D)self
That old man sat down beside me
And he (G) looked me in the eyes
(A) he said son, I know what you're going (D) through
You oughta get down on your knees
And (G) thank your lucky stars
(A) that you got someone to go home (D) to

chorus:
Cuz you don't know (A) about (G) lonely
Or how long nights can (D) be
Until you've lived through the (A) story
That that old man just told (D) me
You don't know (A) about (G) saddness
Or how to face this life (D) alone
You don't know about (A) lonely
Until it's chiseled in stone

So I (D) bought these pretty flowers
Hopin (G) you would understand
(A) sometimes a man can be such a (D) fool
Those (D) golden words of wisdom
From the (G) heart of that old man
(A) showed me I ain't nothin without (D) you

chorus again

pretty basic.  check the video for all the hammer-ons and pull-offs he does.  
when you add those, the song sounds awesome
