All chords in relation to capo
                E  A  D  G  B  e
D               x  5  7  7  7  5
Bm              x  2  4  4  3  2
G               3  5  5  4  3  3
A               5  7  7  6  5  5
I play the D, G, and A this way out of preference, I find it an easier swap from the Bm to a barre G and from
the barre G to a barre A, and the D just sounds higher in the song, so I play it higher up the frets, feel free 
to use a regular D, G, and A chord, it'll sound basically the same.
Listen to the song and you'll get a pretty quick feeling of how the strumming goes.
The intro Bm is only played for a short time, listen and you'll hear it.
