ive watched the video for this song about 15 times to get this 
right and i think it goes
like this:

type: 4 string
tuning: E A D G


verse and chorus
G -------------------------------------------------------------
D -------------------------------------------------------------
A -------------------------------------------------------------
E 3333333333333333333333333333331111111111111111111111111111111

there are a few variations but youll have to work them out 
yourself sorry. the number of notes arent exact but if youve 
heard the song youl know when to change notes.
this is my first tab so its probably not very good
