Last tab i saw of this was ok but kinda wrong and didn't have the part at
the beginning. 
Anyway here goes, main part sounds best in barre chords in my 
oppinion but you can play it with open chords too.


Intro:
This part plays on its own
E-----------------|-----------------|-----------------|-----------------|
B-----------------|-----------------|-----------------|-----------------|
G-12---7---9-9--5-|5-4/12-12-12-7-7-|9-9-5-5-4--------|-----------------|
D-----------9-9--5|-----------------|-----------------|-----------------|
A-----------------|-----------------|-----------------|-----------------|
E-----------------|-----------------|-----------------|-----------------|

This part then plays along with the bass and drums at the beginning and it 
also plays at other parts throughout the song so just stick it in when you hear it!
E-----------------|-----------------|-----------------|-----------------|
B-/1212-7-7--9-9-5|-5-4-------------|-----------------|-----------------|
G--------7-7--9-9-|5----------------|-----------------|-----------------|
D-----------------|-----------------|-----------------|-----------------|
A-----------------|-----------------|-----------------|-----------------|
E-----------------|-----------------|-----------------|-----------------|


Then mostly up strumming of these chords with the singing.
