This is definitely one of my favorite songs in terms of how the chords were
used to achieve a very powerful dramatic effect.

E (022100@1)  eDb (022000@1)    x43121   (x4312x also works if you don't want to bar the fret)

Gdim   34532x   (I use my thumb for the E string; if you think that's
                 "improper" guitar technique just go with 345xxx)
Adim   56754x   (Same as above)
Bdim   78976x   (Same as above; they are all the same shapes)

Verse: Listen to the recording for the rhythm change

If you have trouble with the diminished chords, forget the chords and simply 
strum the E string really hard and go 1-4-5-6-7-8-9-8, preferably with the 
octaves. With vocal on top the chords will come out.

Dramatic pause before the final instrumental part:
