This is just a guess. Sounds pretty close though. Chorus may need some work.

[Capo 3rd]

C       F             C                    G
Shadows fall, and the darkness of night decends
 
C        F               C          G 
Concrete walls bring the road to an end 
        C        F       C                     G
I don't know             which way leads me to you 

      C           F
Every step that i take, 

C                      G
Brings your light into view 

 
BRIDGE
 
Am  F      C                      G
Oooooh  It took so long for me to find you 

Am  F   C                   G
Oooooh  Suddenly our worlds collide
