Great song by scottish rockers GUN. Hope my contribution is appreciated. Probably 
some errors but it sounds OK so give it a try.

GUN - Watching the World Go By  (Album Gallus from 1991)

Intro is same chords and order as verse
--------------------------------------------------------
G       Cadd9             G               D
You say it just scares you when look around
G              Cadd9             G D/Dsus
Things never ever had to be this way
G              Cadd9              G               D
Sometimes when I look at friends, I just see myself
G              Cadd9           G D/Dsus
Now leaving is the price I have to pay

_______________________________________________________

Am
Wish me well
C
You know I've gotta go
           G
You know I've gotta go
              D/Cadd91
I've done my time

Chorus_______________________________________________________

G      Cadd9  G               D
Living without freedom within
G               C      G      D/Dsus
And I'm torn and divided inside
G                Cadd9
Nothing left to give
G                D
Nothing left to lose
G               Cadd9            G
And it's time I've decided to say goodbye

Verse 2________________________________________________

G       Cadd9             G                    D
You say you can never tell what tomorrow brings
G                  Cadd9                           G D/Dsus
But I've been there and I've walked that road before
G                       Cadd9             G      D
Things can change and I look back at the memories
G                    Cadd9                       G D/Dsus
As the night falls, another dream just slips away

Watching the world go by

I've done my time

Living without freedom within
G               C      G      D/Dsus
And I'm torn and divided inside
G                Cadd9
Nothing left to give
G                D
Nothing left to lose
G               Cadd9            G
And it's time I decided to say goodbye
G
Say goodbye

Break_______________________________________________________

F
Born to live till the day we die
C
People talk, tell me who decides
G                       G/Cadd9
Days just pass you by

Life will pass you by

Had enough of the same old scent

Somebody help me

Nothing left to lose
And it's time I've decided to say goodbye
