Flanagan & Allen had a song which they recorded in 1940 during the so-called phoney war:-
If a grey haired lady says 'How's your father'
That will be Mademoiselle,
If she smiles and says 'How's your father'
That will be Mademoiselle,
If she says 'Parlez vous, tout sweet tell me do
How is he after all these years?'
If the grey haired lady says 'Don't tell your mother'
That's mademoiselle from Armentieres!
