I believe the song is written in the key of A, if this helps.
For each riff, I just use the strings 
it uses to save a little space.

Riff 1:
[E---2---0------------------------
B-0---0----0-3--0-2--0-0-0----0--
G--------------------------2-2---]

Riff 2:
[E-4-2-0-5--2-0---4-
B--------------3---]

Riff 3:
[E-4-5-7-7-5-7-7-4-5-]

Intro: B5, play Riff 1, pause, 
play again (second time is actually slightly
different)

B5 (Riff 1 twice, no pause)
Shelter
B5		     A		         E

B5	   A			E	 D     A    B5
I've been exiled, I've been raised within the street, 
in this wicked world
D A B5     A	   E    D      A   B5	 D A
Persecution, I'm carrying my cross, down here on my knees
D (Riff 2) A      B5		   (Riff 1)
No one loves me, anymore, anymore, anymore
D (Riff 2) A	   E

Outro:
[E---------------------
B---------------------
G-----2-4-4-2-4-4-2-4-
D-4-4-----------------]

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

SOLO: don't have it, but it's based on the G G F C pattern 
of the verse then second verse, 
repeating G G F C until the end of the song

         F#m7

Back in seventyfive when the kid was on the line
     Em          G
and he felt no pain 'cause there was none
      D         A
He would bend in the wind, take in anything
         Em           G
like sniffin' roses, and it was all right
      Em          A
until he fell and cut his hand
     G          Bm
He just could not understand
      Em     D/F#      G     E
He ran away, blame pretence for defence
      A
or plain innocence
Said that's all right,
         G        D     A   Em
the harder it fights, I'm one step closer to home

The deeper it bites , I'm one step closer to home
       G           D

Он yeah, he ran, hitched rides, travelled light
      Em       G
left his bags behind, said he lost them
     D           A
He said that's О.К. I got money and a smile
   Em         G
from place to place, and they don't mind

and I just gave them right back again
      Em       D/F#   G       Em
I've got no need for device, disguise

the tougher it gets, I'm one step closer to home

D - C - G/B 
Take a walk round your city walls
Before they all fall down
Take a walk down any street
You're gonna feel the stares of us all
Can you feel it burning
Shame is what it's called
You'd better look at what you have created
Think of all the people who hate you
(Asus4 - A pattern:)
These are the people that made you
When you said you cared for us all
These are the people who'll break you
Get prepared for the fall
(D - Cadd9 - G/B pattern:)

hear our voice, we're growing stronger
marching on, we're not alone now
we're keeping on, we're marching on

D - C - G/B 
power on the right side
fights the power on the left
We have got to stand together
Forget the east and west

'Cause there's another voice crying in the ghetto
Another mouth to feed
Another heart beating in the ghetto
Another soul to set free
(D - Cadd9 - G/B pattern:)
and we'll go marching on, hear our sound,
hear our voice, we're growing stronger
marching on, we're not alone now
we're keeping on, we're marching on
