Old Blues Song...?

This song was performed by 30 Secods to mars, the vocalist (Jared Leto) just said "that's an Old Blues Song".

I want to find the exactly lyric and the real singer...
I have a part of the song but I'm not sure if this is correct u.u...

"You don't turn my head away
Wandering about all by the fields oh no no
There's no place I rather be
I will admit, I'm guilty as you want me to be

Oh Lord, you say you're coming
Oh Lord, if that's the truth
Oh Lord, you say you come
Oh Lord is that the truth? "

I hope you can help me with this song

Here's the song I think...may help to recognise
