Arthur, [note I use the French pronunciation here,]
I can only state, as I did previously:
"Рeu-à-Peu. So George IV. called prince Leopold." Actually, "Marquis Peu-a-peu". Why he did so, I do not know. Perhaps Beau-a-feu?
You can be assured that I have, in fact, watched part of a movie in French - the "French Connection"!
Yours, in firm research,
