as a novice i find the proper chords too hard, these sound close enough
for me, sound ok acoustic, just add capo if needed, i capo 3rd.
this is based on the david gilmour live 2002 version.

Am
Remember when you were young,
F                  C
You shone like the sun.
F     Em Dm  C     G
Shine on you Crazy Diamond.
Am
Now there's a look in your eyes,
F                       C
Like black holes in the sky.
F     Em Dm  C     G
Shine on you Crazy Diamond.

         Am
You were caught in the crossfire
   C
Of childhood and stardom,
Am                 D7
Blown on the steel breeze.
F                      D7
Come on you target for faraway laughter,
C                     Em          E               Am
Come on you stranger, you legend, you martyr, and shine


Solo: Am | ? | C | F | Em | Dm | C | G


    Am
You reached for the secret too soon,
F                 C
You cried for the moon.
F     Em Dm  C     G
Shine on you Crazy Diamond.
Am
Threatened by shadows at night,
F                  C
And exposed in the light.
F     Em Dm  C     G
Shine on you Crazy Diamond.

         Am
Well you wore out your welcome
     C  
With random precision,
Am                D7
Rode on the steel breeze.
F                      D7 
Come on you raver, you seer of visions,
C                        Em         E            Am
Come on you painter, you piper, you prisoner and shine
