I found this tune via Massimo Craveri's youtube channel.
Though he played the tune beautifully, he unfortunately he only knew the A part of the tune. I wrote to the author Eric Thézé and subsequently purchased his music book. I prefer the way the chords sound on my mandolin in D-minor but the A-minor is the key it was written. In either key the tune is beautiful.
Below is whole tune in both in an A-minor version and a D-minor version.
