Gigue des pochards

Although it is stated everywhere (not only on TTA) and by many performing fiddlers, Peter Dawson cannot possibly be the composer of the Gatineau Reel, as he was two years-old when Isidore Soucy recorded the tune in 1938, under the title Gigue des pochards. Now, it does not necessarily mean that Isidore composed it. Here's the abc:
