This is a simplified and adapted (for acoutic guitars) version of the original song.
Standard tuning and no capo. (I think it's 70% correct)

Chords:
B: x244xx
Abm: 466xxx
E: 022xxx
F# 244xxx

Intro.: B (Abm F# E F#)

Abm             F#                        E  F#
I close both locks below the window
Abm             F#                        E   F#
I close both blinds and turn away
Abm             F#                       E  F#
Sometimes solutions aren't so simple
Abm             F#                        E   F#
Sometimes goodbye's the only way

             B    F#               Abm  E
And the sun    will set for you
          B F#               Abm E
The sun   will set for you
              B                     F#
And the shadow of the day
           Abm                      E
Will embrace the world in grey
             B    F#              Abm  E
And the sun    will set for you

Abm F# E F#

Abm             F#                 E  F#
In cards and flowers on your window
Abm                 F#                E  F#
Your friends all plead for you to stay
Abm           F#                     E  F#
Sometimes beginnings aren't so simple
Abm              F#             E   F#
Sometimes goodbye's the only way

             B    F#               Abm  E
And the sun    will set for you
          B F#               Abm E
The sun   will set for you
              B                     F#
And the shadow of the day
           Abm                      E
Will embrace the world in grey
             B    F#              Abm  E
And the sun    will set for you
