I am ashamed to say that I remember this little, inoffensive French priest from his appearance on the BBC TV pop show, The Six Five Special.
Then he sang in English: "Day by day, in the market place I play my flute all day but nobody dances ..."
His name is Father Duval and on this clip he sings the same song,
Father Duval died suffering from alcoholism on 30th April 1984. RIP.
