This are the chords. These are the only chords in the song (in the version i've heard anyway), so get strumming!

e ----------------------------    I don't know the names of the chords. I can't
B ----4-4----------7-7--------    show the rhythm, but it's the right amount
G ----4-4--5--5-5--7-7--4--4-4    of times. This is the acoustic version on the
D ----4-4--5--5-5--7-7--4--4-4    box-set. It would be best to tune half-step, 
A ----2-2--5--5-5--5-5--4--4-4    but not neccesary.
E ---------3--3-3-------2--2-2
