This part (left) repeats for most of the song, sometimes dropping
an octave lower (right).
G------------------------9---|----------------------------------
D--11--7--9--------7--9------|------------------------2---------
A------------7--9------------|---4--0--2--------0--2------------
E----------------------------|------------0--2------------------

There are only a couple variations, one of them being this
(and its equivalent on the lower octave... figure it out):
G---------------------11-9--11-9------------------------9-------
D--11--7--9--------7--------------11--7--9--------7--9----------
A------------7--9---------------------------7--9----------------
E---------------------------------------------------------------



Then in a couple parts of the song, like after Thom sings "Yeah,
it's gone" and at the end of the song, you just play the bit on
the left there, and the part on the right gets thrown in a couple
times too.
G-----------------------------|---------------------------------
D-----------------------------|---------------7-6---------------
A---7-9-9-9-9-9-7-9-9-9-9-9---|---7-7-7-7-7-7-----7---(etc.)----
E-----------------------------|---------------------------------
