The song is in the key of C# minor. 

C#m                        
Saddle up the horses and wear your Sunday best
A
Sing your Sacred Harp, you be holier than the rest
C#m
Fill up the room with a grand and a thunderous song
A
Let it rattle out the windows, let it spill out on the lawn
C#m
Shout, shout your praises to the man who kissed the Lord
F#m
To the back stabbing brother that betrayed all of this world
A  B    C#m
Your Judas! 

(chords remain the same for the rest of the song really)

Yea, though you may walk in the valley in the dark
There's no greater evil than the darkness in your heart
Your stun guns, bloodhounds, needle and your razor wire
Your nylon shackle whipping post and your high tech burning tire
Your Judas! 

Whiplash crack across the back, across the arms
Although you bound his feet, he running fast he running hard
Through them crickets in the corn and them horses in the field
Hear the "caw, caw" of the crows
See the devil at the wheel y'all, Judas! 

Go on down to Alabama, Mississippi, Arkansas,
Oklahoma, Texas, Kentucky, Florida, Louisiana and Tennessee, 
Georgia, Carolina, Carolina.
