I made this tab from this cover: http://www.youtube.com/watch?v=-ofvGKCZk_s (this is not 
my cover, but its the best cover ive seen)
There might be some variations from the original song, so listen to the cover.
There are some variations that i didnt get because of the drums, but this should be 
enough to get you started.
The order of when the parts are played is at the bottom. Enjoy!
