i think the 3 chords at the end are a second guitar. but if you are 
on your own like me, play the last octave note at the 7th fret of the A 
string, rather than at the 12th of the E string, it makes the jump a lot 
smaller. 
 bridge: the other way to play it

Acoustic bit: this could take a while. i'll do both guitars. 
G1 is basically the intro, and it doesn't really stray. 
after a while he starts to strum more, but its the same thing the whole time.

full electrics now 
G1 for 8 bars         G2 comes in after 4 bars with:

B|---------------  ---9-9-9-9-9-9-9-9-9-9-- 
G|--6--4---------  ------------------------  for 4 bars 
D|--6--4--7--4---  ---6-6-6-6-6-6-6-6-6-6-- 
A|--4--2--7--4---  ------------------------ 
E|--------5--2---  ------------------------

then is goes like this. i'm not certain here, but it sounds close. 
its just hte chorus riff whit extra guitar 2.
