Here is a long build-up to a question.
Let's invent a Frenchman. Call him Francois Davout. He was born in a Parisian suburb but at a very early age his family moved to Quebec. He recieved a degree in ethnography from an university there, travels a bit and at last decides to repatraite himself to France. He becomes a fanatical devotee of all things French and true. He even throws out all his Tintins and Lucky Lukes and won't sing along to Aznavour or Macias. He is smitten with traditional French song, before the corrupting influences of Stivell and Malicorne. He writes verses, calls himself les Chants au'Pied (pardon my appalling and nonexistant French) and opens up a myspace page, posting homemade recordings of himself singing French trad leaned from old records, top-line melody only. He loves Au Clair de Lune. My question is, should he sound like this?
