A|----------8--7--6------------------------------------------|

E|------------------9----------9--8--------------------------|
B|-------------4/6-------4/6---------------------------------|
G|-----------------------------------------------------------|
D|----8--6---------------------------------------------------|
A|----------8------------------------------------------------|
E|-6---------------------------------------------------------| x1

the intro is played as the verse, but there is one variation: after the first time you 
1 the first time instead of playing it again you play

E|-----------------------------------------------------------|
B|-----------------------------------------------------------|
G|-----------------------10--8---6---------------------------|
D|----8--6---------------11--10--8---------------------------|
A|----------8--7--6------------------------------------------|
E|-6-----------------(6)-------------------------------------| x1

and then the part where he sings "...like being in a large....humanarium"

E|-----------------------------------------------------------|
B|-----------------------------------------------------------|
G|--9--------8-----------------------------------------------|
D|--11-x16---10-x9-------------------------------------------|
A|-----------------------------------------------------------|
E|-----------------------------------------------------------| accent on the last 10/8.
the same with the large nigerian part.

riff 2: CHORUS

E|-----------------------------------------------------------|
B|-----------------------------------------------------------|
G|--9---9----8---8----6--6---10--10--------------------------|
D|--11--11---10--10---8--8---11--11--------------------------|
A|-----------------------------------------------------------|
E|-----------------------------------------------------------| x3 start it a 3rd time but
after the 2nd 10/8 and play

E|-------------------------------------------------------------|
B|-------------------------------------------------------------|
G|--8--8--8---10-10-10--8--8--8---6-6-6------------------------|
D|--10-10-10--11-11-11--10-10-10--8-8-8------------------------|
A|-------------------------------------------------------------|
E|-------------------------------------------------------------| x3
[--------------------PALM MUTED------------------------------|

E|-----------------------------------------------------------|
B|-------------------------14----------14-13-----------------|
G|--8--8--8---10-10--8/10--------8/10------------------------|
D|--10-10-10--11-11------------------------------------------|
A|-----------------------------------------------------------|
E|-----------------------------------------------------------| x1

i havent figured out the double-stops for the part where he sings "special, special
but the basic notes are

E|-----------------------------------------------------------|
B|-----------------------------------------------------------|
G|--6-6-6-6-6-6--4-4-4-4-4-4--6-6-6-6-6-6--4-4-4-4-4-4-------|
D|-----------------------------------------------------------|
A|-----------------------------------------------------------|
E|-----------------------------------------------------------|

he could be playing the notes with a lot of muted strings to make it sound better. the
bassline for the verse is

E|------------------6----6-----------------------------------|
B|-----8-6------------------------8-6---------------6-7-8----|
G|----------8-7-6----------------------8-7-6-----8-----------|
D|--6--------------6----6-------6--------------6-------------|

chorus

E|-----------------------------------------------------------|
B|-----------------------------------------------------------|
G|--9--9----8--8---------------------------------------------|
D|------------------6--6----9--9-----------------------------|
