I'm pretty sure this is how to play this song... It's how i play it and it sounds right...

G|————1———————————|————1———————————|
D|2—2———2—0———————|2—2———2—0———0———|
A|——————————3—2———|——————————3———32|
E|————————————————|————————————————|

^ THATS THE MAIN RIFF

When it reaches the break (O rat least taht's wehat I call it...):|

G|————————————————|
D|————————00000000|
A|33333333————————|
E|————————————————|

And then back to the main riff. Listen to the song to find where to play the different parts 
because I am doing this tab by memory...
