[SALLY, spoken]
If anyone should ask you about me one day, Cliff
You have two alternatives:
You can either say, “Oh, yes, it's true. We're living in delicious sin.” Or you can simple tell the truth, and say

[SALLY]
I met this perfectly marvellous girl
In this perfectly wonderful place
As I lifted a glass to the start of a marvellous year
Before you knew it, she called on the phone, inviting
Next moment I was no longer alone
But sat reciting
Some perfectly beautiful verse
In my charming American style
How I dazzled her senses
Was truly no less than a crime
Now I've this perfectly marvelous girl
In my perfectly beautiful room
And we're living together
And having a marvellous time

[CLIFF, spoken]
Ah Sally, I'm afraid it wouldn't work
You're much too distracting

[SALLY, spoken]
Distracting? No, inspiring!
[SALLY]
She tells me perfectly marvellous tales
Of her thrillingly scandalous life
Which I'll probably use
As a chapter or two in my book
And since my stay in Berlin was to force creation
What luck to fall on a fabulous source of stimulation!
And perfectly marvellous too
Is her perfect agreement to be
Just as still as a mouse
When I'm giving my novel a whirl
Yes, I've a highly agreeable life
In my perfectly beautiful room
With my nearly invisible
Perfectly marvellous girl

[CLIFF]
I… met… this
Truly remarkable girl
In this really incredible town
And she skillfully managed
To talk her way into my room

[SALLY]
Oh, Cliff!
[CLIFF]
I have a terrible feeling I've said
A dumb thing
Beside, I've only got one narrow bed

[SALLY]
We'll think of something

[CLIFF]
And now this wild, unpredictable girl

[Sally]
And this perfectly beautiful man

[BOTH]
Will be living together and having a marvellous life!
