As I've seen live vocalist/guitarist using capo on 4th fret for this song

Used chords are (remember, that 4 fret means open)

G#add9   F#6    G#/F   D#m7   Fm7    G#

e|-6------6------4------6------8-----4---|
B|-4------4------4------7------9-----4---|
G|-5------6------5------6------8-----5---|
D|-6------4------6------8------10----6---|
A|-x------6------8------6------8-----6---|
E|-6------x------x------x------x-----4---|


INTRO
Basically it's just strumming the G#add9 chord with lots of reverb, delay and other effects.

Then, when the bass coming in strum these
G#add9   F#6    G#/F

The same thing is going on in a VESRE and it goes like this

G#add9
Stumble in my head I never would imagine

F#6                         G#/F
Uour lips could be so red a cherry colored heave

(etc.)

CHORUS (it's looks stupid, but I hope you'll understand)

D#m7
Aaaaaaaaaaaaaaaah Aaaaaaah           \
Fm7                G#                 | - 2 times
Aaaaaaaaaaaaaaaaah Aaaaaaah Aaaah    /

Then song kinda repeats musically and it goes verse, chorus again and again
Outro is the same as the intro - just strumming G#add9 chord.
And that's it.

Still, if you want to play it without capo or on acoustic guitar, you can just use these 
chords (instead of those I gave you before)

                           [E-B-G-D-A-E
Instead of G#add9 use A#m (6-6-6-8-8-6)
Instead of F#6 use D#m
Instead of G#/F use Fm

A#m
Stumble in my head I never would imagine

D#m                         Fm
Uour lips could be so red a cherry colored heave

etc.

I hope it will help.
