Oh Oh Oh
I I was a city boy 
Riding to danger's
where I'd always run
above and is hurt 
I wouldn't have done 
All the things
that I've done 
If I knew one day 
You would come 
Now baby now baby now baby 
Oh oh oh
I I know
it breaks your heart 
To picture the only one
you wanna love 
In someone else's arms 
But I wouldn't have done 
All the things that I've done 
If I knew one day
you would come 
Now baby now baby now baby 
Oh baby please 
Let's leave the past behind us 
behind us 
So that we can go
where love will find us 
Yeah will find us 
I know once girls
would leave me 
But I know that
you believe me 
Baby I I I wish
we were seventeen 
So I could give you
all the innocence 
That you gave to me 
No I wouldn't have done 
All the things that I have done 
If I knew one day you would come 
If I knew one day you would come
