I'm running with a Strat with a crappy set of single coils that can't harmonize to save 
lives...also missing bottom string and have no money to get new one.  So I'm giving you 
basics.  You can figure them out.

* = Played octave higher
() = harmony
^ = slight bend
> = slide up
< = slide down

Intro:
   *F#5         D5      E5     *B5
B|------------------------------12---|
G|------------------------------11---|
D|--11-11-11-11-7-7-7-7-9-9-9-9--9---|  repeat 4xs
A|---9--9--9--9-5-5-5-5-7-7-7-7------|  (4th time let B ring out)
E|-----------------------------------|

Verse:
    *F#5 D5 E5 *B5       *F#5 D5 
*B5
B|-----------------(12)-----------------12-15-12---|
G|-------------------------------------------------|

    *F#5 D5 E5 *B5       *F#5 D5 E5 *B5 -->
B|----------------------------------------|
G|-----------------(13)-------------------|

Thats all the verse harmonies I could make out

PreChorus:  F#5

Chorus:

(I have no E string so I play this way.  Feel free to experiment)

B|--------15---14------------|  repeat 4xs
G|----------------13-11-10---|
D|---12----------------------|

Guitarist plays C#5 and another chord...figure it out

PostChorus:

B|------>-14-12--------------------|
G|---11-------------->-13--11--9---|  2xs
D|----------------11---------------|

D|-------4---4-6-7-6-4-2-4--4-6-4---4-6-4-2---|
A|--------------------------------------------|
E|---2----------------------------------------|

D|-------4---4-6-7-6-4-2-4--4-6-4--4-2-4--4-2-4-6-4-2---|
A|------------------------------------------------------|
E|---2--------------------------------------------------|

Verse 2 is same chords as verse 1 with little variations

Verse break:
*F#5 *F#5 *F#5 *F#5 *Ab5 *F5 
*F5 *F#5 *Ab5 *F5  (2xs)

You?re on your own for the solo.

Outro:

F#5   A5   C5   F5 E5 F5 
F5   C5 C5 B5 B5    F#5
