Well now.... the Northumbrian pipes clearly have something in common with 18th century French musettes. And conversely, the Bretons have adopted Highland bagpipes, probably as a result of First World War contact. Stylistically, cross pollination at least of dance tunes seems to be recent though- you don't get bourrees in England or Scotland, and the Schottische is decidedly not Scottish. My knowledge of the pre- revival French folk repertoire and the pre- collector age Atlantic Islands repertoire is pretty limited, but as far as I know you don't get stuff like Anet or Boismortier in England. Our aristocrats didn't play at being shepherdesses.

France was of course the major destination of aristocratic and upper- bourgeois Grand Tourists of the 18th century- mainly the super- rich continuing to Italy- and they would have had some servants with them. But they would have been hand- picked trusties who saw themselves as a cut above the common slaveys, and consequently a poor conduit between the demotic cultures.

Hmm. Jack Campin?
