ok. lets do this.

the guitar riff / verse goes like this ( at least this the power chord version)

 1 ----------------------------------------------------------------|
 2 ----------------------------------------------------------------|
 3 ---------7-----7-7-7-7------------------------------------------|
 4 ---7---7-7-7---7-7-7-7*-7---------------------------------------|
 5 ---7---7-5-7---5-5-5-5--7---------------------------------------|
 6 ---5---5---5------------5---------------------------------------|

*this part can be played a couple of ways. you can do 8 strums instead of 4, or 1 
of 4. also, you can play the riff differently where one part is up the neck. i think tht going 
and down the neck makes you look better. this is how
 1 -----------------------------------------------|
 2 -----------------------------------------------|
 3 ---------7-------------------------------------|
 4 ---7---7-7-7---12-12-12-12--(optional)--7------|
 5 ---7---7-5-7---12-12-12-12--slide down -7------|
 6 ---5---5---5---10-10-10-10--------------5------|

the chorus goes like this
 1 ------------------------------|
 2 ------------------------------|
 3 ----------7--7-7-7-7----------|
 4 --7-7-7-7-7--7-7-7-7-7--------|
 5 --7-7-7-7-5--5-5-5-5-7--------|
 6 --5-5-5-5------------5--------|

again, to add style, you can do this

 1 ---------------------------------------------|
 2 ---------------------------------------------|
 3 ---------------------------------------------|
 4 --7-7-7-7-12--12-12-12-11-9-7----------------|
 5 --7-7-7-7-12--12-12-12-11-9-7----------------|
 6 --5-5-5-5-10--10-10-10-9--7-5----------------|

there you go
 rock on
