E--2-2--2-2-2--2-3-3--3-3-3--3-5-5--5-5-5--5-3-3--3-0-0--0
B--3-3--3-3-3--3-3-3--3-3-3--3-3-3--3-3-3--3-3-3--3-3-3--3
G--2-2--2-2-2--2-4-4--4-4-4--4-5-5--5-5-5--5-4-4--4-0-0--0
D--0-0--0-0-0--0-0-0--0-0-0--0-0-0--0-0-0--0-0-0--0-0-0--0

Repeat this line once, then :

E--10-10--10-10-10--10-12-12--12-12-12--12-13------12-----
B--11-11--11-11-11--11-13-13--13-13-13--13-15------15-----
G--10-10--10-10-10--10-12-12--12-12-12--12-15------15-----
D--0--0---
A--
E--

Then the main guitar riff starts :

sl=slide down (as the chord dies)

E--
B--7-sl----5--7-7-sl----3--5-5-sl----3--5-5---5--7--5-
G--7-sl----6--7-7-sl----4--5-5-sl----4--5-5---6--7--6-
D--7-sl----7--7-7-sl----5--5-5-sl----5--5-5---7--7--7-
A--5-sl----4--5-5-sl----2--3-3-sl----2--3-3---4--5--4-
E--

This repeats quite a few times

That second shape is a bit awkward when you first see it
I finger it like this :

EADGBE
------
1 1=first finger
------ :
2 :
------ 4=little finger or pinky if you like
3
------
4
------ 7th fret

You have to be careful to mute or not strike the top and
bottom Es too!

I mute the top one using my first finger

The rest of the chords are easier you'll be glad to know
It goes :

A D/A
One flesh one bone one true religion

A D/A
One voice one hope one real decision

C Csus4 C
wo-oo-oo-oo-oo-oo give me one vision

A5 Bb5 B5 C5 C#5

then back to the riff

Chord shapes :

EADGBE EADGBE EADGBE EADGBE EADGBE EADGBE
x0222x x0423x x3555x x3556x x022xx x133xx

A D/A C Csus4 A5 Bb5

..and so on for B5, C5 - just move it up fret by fret

The intro chords come in again over the middle 8 : 'I
had a dream , when I was young ..' etc
