Here is the general riff played through most of the song

E |-------------------------------------------------------------------------|
B |------4--4-4--4------7---------4-4--4------------------------------------|
G |------4--4-4-------------------4-4--4h6--6-----4-------------------------|
D |----------------------------4--------------------------------------------|
A |--2--------------2s6-----------------------------------------------------|
E |-------------------------4-----------------------------------------------|

The E and F# are the beginning of the Chorus and the riff always follows

E |-0---2-------------------------------------------------------------------|
B |-0---2-------------------------------------------------------------------|
G |-1---3-------------------------------------------------------------------|
D |-2---4-------(insert riff here)------------------------------------------|
A |-2---4-------------------------------------------------------------------|
E |-0---2-------------------------------------------------------------------|

Brett embellishes with some variations here and there in the riff and the E and F#, so 
free to add what you want,
but this is the jist of it here. Finally, tell your friends about this guy, he's a great 
that more should hear.


Enjoy
