This is just a guess. Sounds pretty close though. Chorus may need some work.
[Capo 3rd]
Shadows fall, and the darkness of night decends
Concrete walls bring the road to an end
I don't know which way leads me to you
Every step that i take,
Brings your light into view
BRIDGE
Oooooh It took so long for me to find you
Oooooh Suddenly our worlds collide
CHORUS
I'll never let you go,
i'll never let you go
I found you and now i know
That i'll never let you go
