I haven't figured out the ending where he goes insane but here is everything leading up 
that...and for this version it is just normal tuning

This is my first tab, so i hope it makes sense...

(X-2)= cover 2, but dont hold the note
***= Let the note Ring


Intro
-----------------------------------|
-----------------------------------|
-----------------------------------| (repeat)
-----------------------------------|
-----------------------------------|
2-***--0-5-2--***-0-5-2--***-0-5-2-|

------------------------------------|
------------------------------------|
------------------------------------| (repeat x4)
------------------------------------|
(X-2)***----4-4-4-4-4---4-4-4-4---7-|
(X-2)***----2-2-2-2-2-0-2-2-2-2-0-5-|

From there ^^ go back into the intro riff

---------------------------------------|
---------------------------------------|
---------------------------------------|
---------------------------------------|
4-4-4-4-4-4-4-4-4-4-4-4-4-4-4----------|And back into the intro
2-2-2-2-2-2-2-2-2-2-2-2-2-2-2----------|And back into the intro

After Playing the intro and hearing some singing it goes into the more fast paced 
of the intro like this:

---------------------------------------------------|
---------------------------------------------------|
---------------------------------------------------|
---------------------------------------------------|
4--4--4---4-4-4---7-(repeat)---then----4--2--7--5--|(repeat the same way)
2--2--2-0-2-2-2-0-5-(repeat)---then----2--0--5--3--|(repeat the same way)

around 4:12 theres a little:

---------------|
---------------|
---------------|
---------------|
---------------|
0--5-2---------|


And thats pretty much the whole song except for the ending...Hope you can understand this!

Thanks!
