I once saw a copy of a biography of Kathleen Ferrier that had a photocopy of one of her letters (typed and signed) inside it. She quoted this limerick:

There was a young lady of Nantes
Who was tres joli et piquante.
But her hole was so small
It was no good at all
Except for la plume de ma tante.

I've heard from other sources that Ferrier was fond of bawdy stuff. I wonder if there are any clandestine recordings of her singing it?
