And the strumming is just palm-muted barre chords
barre E- 9th fret
barre Em- 6th fret
barre Em- 1st fret

play that through the entire song, and every fourth time you play that, there is a barre 
E 4th fret.

otherwise, you could play it through with a capo on the first fret so it's like
C,Am,Em
C,Am,Em
C,Am,Em
C,Am,Em,G


Listen to the song, and this should all make sense!
