Happily Gilles Losier is still in the land of the living (last I heard) and what a great multi-cultural, gap-bridging guy he is.

A few years ago at Champlain Valley, fiddlers from all over were playing "stump Gilles"... ...trying to find tunes he wouldn't recognize (all in good fun). But he invariably came out with something like: "Oh yeah, that's St Possumtrot Reel, first recorded in 1923 by Fingers McGee." (which would turn out to be correct).
