LILY:
How could I know I would have to leave you?
How could I know I would hurt you so?
You were the one I was born to love!
Oh, how could I ever know?
How could I ever know?
How can I say to go on without me?
How, when I know you still need me so?
How can I say not to dream about me?
How could I ever know?
How could I ever know?
Forgive me.
Can you forgive me
And hold me in your heart,
And find some new way to love me
Now that we're apart?
How could I know I would never hold you?
Never again in this world, but oh,
Sure as you breathe, I am there inside you,
How could I ever know?
How could I ever know?
ARCHIBALD:
How can I hope to go on without you?
How can I know where you'd have me go?
How can I bear not to dream about you?
Oh, how can I let you go?
LILY:
How could I ever know?
ARCHIBALD:
All I need...
LILY:
Is there in the garden!
ARCHIBALD:
All I would ask...
LILY:
Is care for the child of our love!
Come, go with me, safe I will keep you.
ARCHIBALD:
Where you would lead me, 
There I would,
LILY:
There I would, there we would,
ARCHIBALD and LILY:
There we will go.
Oh! How could I know?
Tell me how could I know?
Never to know you would ever leave me!
How could we know?
LILY:
How could I ever know?
