kay so i'm too lazy to tab out the songs chords with all the lyrics and times so i'm 
just tab the intro and backing part and tell you the chords.

intro

E-------------------------------------------------------------------|
B-------------------------------------------------------------------|
G---------9------------9-------9----4-------------4---------4-------|
D--------------7-----6------6------------2------1---------1---------| 
A-------9----9---7-------7-------4----4------2---------2------------|
E-------------------------------------------------------------------|

E-------------------------------------------------------------------|
B-------------------------------------------------------------------|
G---------9------------9-------9----4-------------4----4------------|
D--------------7-----6------6------------2------1------1------------| 
A-------9----9---7-------7-------4----4------2---------2------------|
E-------------------------------------------------------------------|

Then it switches into chords

A B E  C#m  B


It?s those chords for the whole song I think. The order and strumming just changes slightly

The verse and bridge go like this:    A  E  C#m  B

The prechorus goes: A  C#m  B

The chorus is:  E  B  C#m  A

During the chorus a guitar in the background plays this


E-------------------------------------------------------------------|
B-------------------------------------------------------------------|
G-----------------------------------4444----------------------------|
D?2222444466664444(x2)--222244446666----(2x)------------------------|
A-------------------------------------------------------------------|
E-------------------------------------------------------------------|


And during the verse I think the backup guitar plays a rhythm with the 8th and 9th frets 
the G string. And that?s it.
