This is what I got from listening to that recording:

Will you be my darling,
My honey bun?
Will you be my darling,
My only one?

You've got the love light [right?] in your eyes,
I've got a heart that's just your size.

Will you be my darling?
I think you might,
Will you be my darling
And start tonight?

Could you learn to love me as I love you?
Will you be my darling and make my dreams come true?

If I'm remembering correctly from years back, Roy and Dale's version used some alternate lyrics that went like this:

Will you be my darling
My only one?
Will you be my darling?
It might be fun....[etc]

And in the last verse:

Will you be my darling
And hold me tight,
Will you be my darling
And start tonight?

Could you learn to love me, etc...
