I was listening to the song and I personaly think 
the beggining of the soung sould be played like this.
                               
(1)         (without distortion)
e-----------------------------------------------------                          
b-----------------------------------------------------
g-----------------------------------------------------
d-----------------------------------------------------
a-3--5--3-5-5-3--5--5b-5--3--5--3--5------0--3--3/5b--
d-0--0--0-0-0-0--0--0--0--0--0--0--0---0--------------



(2)                                (distortion)
e------------------------------------------------------
b------------------------------------------------------
g------------------------------------------------------
d------------------------------------------------------
a-3--5--3-5-5-3--5--5b-5--3--5--3--5---1-1-3-3-0-------
d-0--0--0-0-0-0--0--0--0--0--0--0--0---1-1-3-3-0-------

(3)
e------------------------------------------------------
b------------------------------------------------------
g------------------------------------------------------
d------------------------------------------------------
a-3--5--3-5-5-3--5--5b-5--3--5--3--5-5-3-3--5-5-0------
d-0--0--0-0-0-0--0--0--0--0--0--0--0-0-3-3--5-5-0------

Then he starts to sing and you repeat (1) about 4 times, have fun!
