Back when I was playing a lot of button accordion, I knew this tune as Le Reel de Ste-Anne. These days I play mostly clawhammer banjo and in the banjo world, the tune is more generally known as The St. Anne’s Reel.
Either way, it’s usually played in the key of D and I have my banjo tuned to “double D tuning”, which is aDADE.

Sounding good, Eugene! I would love to hear a duet between you on clawhammer banjo and you on button accordion!
I’ve thought about trying to record something with both instruments….maybe I’ll get around to it someday.
