Who... who... who...
Is it really you?
With all that I have seen and done
It seems that only dreams
Could bring you back to me
Who... who... who...
And after all these years
I'm still asking myself
What could have made me blind
To walk away from you
Who... who... who...
Now I'm standing in a crowd
Trying to find a way to you
But every face I see is new
And all the memories run through
Who... who... who...
Oh, who could have known?
Oh, how my heart aches for you
Oh, who could have turned from you?
Who... who... who...
And now it seems so long ago
Since I was the only one for you
And I'm so lonely, I could die
Who... who... who...
Oh, who could have known?
Oh, how my heart aches for you
Oh, who could have turned from you?
Oh, now I'm standing in a crowd.
