None of the other tabs for this song were doin' it for me, so here's how I think 
it should be played:

CAPO 3rd Fret

Just three chords for the entire song:

Em C G

Alternatively, you can not use the capo and use barre chords instead:

  Gm Eb Bb
e-3--6--6--|
b-3--8--6--|
g-3--8--7--|
d-5--8--8--|
a-5--6--8--|
E-3-----6--|
