Hello julo59G, the score already on the site does not correspond to the music of Roger Sy. This Polka was played by Pascal Bourg in 2017 at the festival night Ségurel Special Roger Sy in Chamberet (19).
The handwritten copy that Ducon has deposited lately corresponds to this polka but is incomplete compared to the interpretation of Pascal Bourg.
I wish you a good day.
