there is another tab on this site but i find it sounds alot nicer if you play the following: E :-2-2-2-2-2-2-2-2-0-0-0-0-0-0-0-0-| B :-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-| G :-2-2-2-2-2-2-2-2-0-0-0-0-0-0-0-0-| D :-0-0-0-0-0-0-0-0-0-0-0-0-0-0-0-0-| A :---------------------------------| E :---------------------------------| This is the main riff and it is incredibly easy to play, it is just based around the D and it sounds great on an acoustic guitar.
