this song is pretty simple, for the first part play 2 times without distortion, 
then 4 times with distortion.

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

note: for last chord you may also use D-7
                                      A-5
                                      E-5

to play the main verse it is easier to use a ditital delay or echo, but if you dont
have either of those effects pedals, you can just use "echo picking"

E--------------------------------------------------
B-12-12-----------------12-12-----------10-10-10---
G------11-11-12-12-9-9-9-----11-11-12-12-----------

that should be the first two parts, part one is the intro plus the chorus, part two
is the main verse.
