Guillaume, you extracted "Ce sont trois galions d'Espagne" and "La bébé" (aka La polka des bébés) from Marie-Marguerite Andral and Claudie Marcel-Dubois' field recordings (1970?) from Sark. Where did you find them? Are they in the Bibliothèque Nationale? I already know about Peter Kennedy's recordings (1957 - 60), Locke and Anderson's tapes (Sark; 1976) and the BBC recordings of the Sark Singers (1938), but I would be interested to know whether Andral and Marcel-Dubois collected anything that the others had missed.
