This song is very long and repetitive, so I'm not counting how many times you have to 
repeat each part...

Mostly play this:
E|-------------------------------------12------10------12------10----|
B|---10--10--10--10--10--10--10--10--10--10--10--10--10--10--10--10--|
G|-12--12--12--12--12--12--12--12--11------11------11------11--------|
D|-------------------------------------------------------------------|
A|-------------------------------------------------------------------|
E|-------------------------------------------------------------------|

But sometimes just repeat this:
E|-----10------10------10------10------------------------------------|
B|---10--10--10--10--10--10--10--10----------------------------------|
G|-12------12------12------12----------------------------------------|
D|-------------------------------------------------------------------|
A|-------------------------------------------------------------------|
E|-------------------------------------------------------------------|

"Heavy" part: easier with capo on 5th (maybe even in drop D)
play 1st bar many times,
then 2nd bar many times,
then repeat last 2 chords many times

E|-55555555555555555555555555555555-|------------------|-5----5------|
B|-88888888888888885777755557777555-|--5-5-5-5-5-5-5-5-|-8----8------|
G|-77777777777777777777777777777777-|-7777777777777777-|-7----8------|

E|----------------------------------|------------------|-------------|

(there's actually lots of things going on, but this should take care of most of the 
notes that are being played)
