INTRO: appregio based on G F F Em bar chords, something like:

E|-----3--------1--------1--------0---|
B|--------3--------1----------------0-|
G|------------------------------------|
D|---5--------3--------3--------2-----|
A|----------------------------2-------|
E|-3--------1--------1------0---------|

This figure repeats throughout the verses.

At one point in the first verse, this changes slightly:
(sorry, don't have exact lyric with me)

G      F              F       Em
I have drunk from fire water

G            F             F      Em    D   C
Free spirits rising in the world

and then above figure repeats again.

CHORUS:

G         F                 C
Raw, raw, burnt back to the bone

G                    F                C
Raw, raw, you better leave this child alone

G         F              C
Raw, raw, I ain't got no home...now

F                  F
Burnt right back...burnt right back to the bone.

G G (rake) G G (rake) F F (rake) F F (rake)...then back to the verse.

BRIDGE: (after second chorus)

D
Rolling like a river, running like a train

D                   C      G
Free spirits rising in the world today
