The whole song is just G D C throughout with a capo on the first fret. The beginning 
a little something like:

e-3------3----------2--2--------0--0---0---0---0-|
B-0--0------0---0---3----3------1--1---1---0-----|h1
G-0----0------0-----2------2----0--0--h2---0---0-|
D-0-----------------0-----------2--0---0---2---2-|
A-2-----------------0-----------3--3---3---3---3-|
E-3-----------------------------3--3---3---3---3-|

The do the chord progression throughout the song. And it's in 5/4 timing.
