The intro is double-tracked: 
 
e-----------2p0--------------------2p0---------------------------------------- 
b---------0-----3p0--------------------3p0------------------------------------ 
g---------------------0----------3----------0--------------------------------- 
d------4-----------------------4---------------------------------------------- 
a----2-----------------------4------------------------------------------------ 
E--0----------------------2--------------------------------------------------- 
 
The main rythym is: 
 
e---9\----7-7---------------------7------------------------------------------ 
b---10\---8-8---------------------7------------------------------------------ 
g---11\---9-9---------------------7------------------------------------------ 
d---------------7-7-7-7-8-9-7-----7------------------------------------------ 
a-----------------------------7---------------------------------------------- 
E------------------------------0--------------------------------------------- 
 
During the Lyrics its: 
 
e-----9----7------------5------------------------------------------------------ 
b-----10---8--------9---7------------------------------------------------------ 
g-----11---9--------9---7------------------------------------------------------ 
d-------------------9---------------------------------------------------------- 
a------------------------------------------------------------------------------ 
E--0------------0-------------------------------------------------------------- 
 
The bridge sort of thing is: 
 
e----------------------------------------------------------------------------- 
b--9--7-8-9--9-7-8-9-7-9-10--------------------------------------------------- 
g--9--7-8-9--9-7-8-9-7-9-10--------------------------------------------------- 
d--9--7-8-9--9-7-8-9-7-9-10--------------------------------------------------- 
a----------------------------------------------------------------------------- 
E----------------------------------------------------------------------------- 
 
The ascending bit is played in two octaves.  The lower one goes like this: 
(Im probably making a mistake near the end of this) Play this one out, 
then (I think) play it again an octave higher. 
 
e---------------------------------------------------------------------------- 
b---------------------------------------------------------------------------- 
g-------------------------------------------------------9-------------------- 
d-----------------------------------9----/10----/12-------11----------------- 
a-2---/3---/5---/7---/8-----/10-------10-----12-----14----------------------- 
E---3----5----7----8----10------12------------------------------------------- 
 
Here's the start of the solo(and it'll probably have a couple of errors 
as well) 
 
e--------7----------------------------------------------3-3h5p3------------- 
b-----5-----7--5-5---8^10^8---------5-5---3-5-3h5p3--5--5-5------7-5-5------ 
g--/4------------------------7^9^7--5-5--------------5--4-4------7-5-5------ 
d--------------------------------------------------------------------------- 
a--------------------------------------------------------------------------- 
E--------------------------------------------------------------------------- 
 
 
e------7-------------------------------12-14-15--14h15p14p12--14h15p14p12--- 
b----5----7--5-5--8--10--7h8p7-10^12---------------------------------------- 
g-/4------------------------------------------------------------------------ 
d--------------------------------------------------------------------------- 
a--------------------------------------------------------------------------- 
E--------------------------------------------------------------------------- 
 
                              Then it breaks  down and basically stays in 
                              XIV position for a while. 
e--12--15--12--15^17-------------------------------------------------------- 
b---------------------13-13------------------------------------------------- 
g--------------------------------------------------------------------------- 
d--------------------------------------------------------------------------- 
a--------------------------------------------------------------------------- 
E--------------------------------------------------------------------------- 
 
The only other part I can remember goes something like this: 
 
e------0------0------0--------------------------------------------------------- 
b----0------0------0----------------------------------------------------------- 
g--------------------------------------------------------------------------- 
d--------------------------------------------------------------------------- 
a-------------------------0-------------------------------------------------- 
E--0------2------3------3/5--3-2--1------------------------------------------
