I kinda got tried of the complicated versions, so here's a really simple one

e----------------------------------
b----------------------------------
g----------------------------------
d---------333---------555----------
a---333---111---555---333----------
e---111---------333---------------- play 3 times in a down,down,up motion
pause a moment and play

e---1-
b---1-    w   then play again and so on.
g-----    a   
d-----    i  
a-----    t  
e-----

Then play the intro riff with distortion for the chourus

My band's backup guitarist played this for a gig and we did fine.
