Tabbed directly from Alex playing live it is 100% correct and this is
the version I play link http://www.youtube.com/watch?v=b9cK6ywLooE&fmt=18
Capo 1st fret he has his on the second but I think his guitar is down a
half step
Im only going to put up the chords in the order they are played the
strumming pattern is down up down up repeated and hard down strokes on
the fifth stroke but the pattern doesnt matter so much if you just follow
the song no one can tell the difference
An * means he only strums once
An ^ means when he plays that part he only plays down strokes and only plays
the main strings of the chord while he pulses his hand to mute it
