hi everyone

I need the tabs for the song in this scene of supernatural (S02E08)
Crossroads Blues

It is not Robert Johnson's Crossroads Blues
It was made only for this Scene

Can anyone help me?
I can't get the song out of my head xD
ehm sry but, it is not "Me and the Devil Blues" Some pieces of this song are maybe also there, but it is not this song ^^
I wonder if its a mesh of a few of his songs... hm. Sorry about that. I'm curious about it now too, so if I figure it out before anyone else replies, I'll make sure I let you know!
Days go on forever
But I have not left your side
We can chase the dark together
If you go then so will I
