Tuning is E, A, D, G (standard) I only wrote down the A and E strings 
because the others aren't used.
/ = Slide up
\ = Slide down

I'm pretty sure this is 100% correct but there could be a few minor mistakes in the fast bits.

The verses are played really fast, there are no quiet bits between each line but I wrote 
each line separately to make it clearer. I also wrote the lyrics in aswell so you don't get lost.

I'm only happy when it
    Raaa-aaaains
