Hey, I've been fiddling around with "go to sleep" from what I've seen Seth doesn't use a capo, but I found it pretty easy if you capo the second fret and then the basic rythm is an E and an A chord

Lay back, lay back go to sleep my man....
E A
wipe the blood from your face and your hands....
E A
Forgive your self if you think you can.
E A
Go to sleep, go to sleep my man.
A E B E

Etc.... and obvously without the capo its a F#, B and C#
