Further to Bernard's posting above - there is another verse I remember:

He:
Darling go home, the will's to be read,
She:
What's that you said?
He:
I said the will's to be read!

She:
Oh no my dear Franz,
This is no time to dance,
I must go home to my poor old man,
I must go home to my poor old man!

The duo Nina and Frederik rings a bell for this one, it was the sort of thing they did.

Cheers
