So this is the main bass riff played. There are slight variations in the song here and 
there but this is the jist of it.
Please note that this does not apply to the Live version of the song as it is slightly different.


G -----2-4-2---2-4-|-----2-4-2---2---|
D ---4-------4-----|---4-------4---2-|
A *2---------------|*2---------------|
E -----------------|-----------------|

*These notes should be accented

This is played pretty fast and you will need to play it with the song to get the timing right.

Enjoy
