Use the words from another tab but the chords for this song are:
Capo third fret and:
D                      G
I am a man of constant sorrow
          A              D
I've seen trouble all my days
                         G
I bid farewell to old Kentucky
                A              D
The place where I was born and raised
                 A               D
(The place where he was born and raised)
The performance I saw seemed to be tuned in DADGAD but if you are just trying to use a 
tuning to jam on, like me, this works.
