Saw tabs for this around the place. They had a few mistakes on them (and mine are far 
from perfect) thought I'd show my own attempt:

The bulk of the song is just this repeated. There are some slight variations throughout 
the song but it should be clear which part to play when. If I have any further 
improvements, I'll try to add them later.
