I saw a few tabs for this song but I felt they were both incorrect and Didn't do 
this song any justice. It's an amazing song! This is a pretty accurate guitar tab 
of the song, I believe, based on the version of Coffee in "Beneath Medicine Tree". 
I hope my work has paid off and will help you out. Enjoy and tell me what you think!

/ = slide
h = hammer on
