a French Canadian might be able to help.

It sure is amazing .. what a spectrum of styles out
of such a "simple" instrument

Yeah, sounds like Québécois or maritime. I believe Maz can help you.

I agree it sound French Canadian...though it has an eastern european/Chech lilt to it as well.

Ain't it amazing what a little one row diatonic can do?

La Pointe aux Piques (or Pointe au Pic), by Marc Savoy and Steve Riley, is a similar tune.

Marc.

You probably already know this, but the accordionist is Frank Sears. I think I might have the sheet music for this song if you're interested. I love this guy's playing, it's very tasteful!

These guys are absolutely amazing. Also the guitar player. Very original backing!
The style is 100% Quebecois. It's maybe the best example you can find. A bit in the school of Philippe Bruneau. Hard to pick up, because it has a complete different approach than Cajun. Much lighter and more staccato.
I tried it too, see website #2, but you can't compare my effort with what these guys do.
If you really want to learn this tune, dl it with Youtube dl-er, and play it over and over again.
If you have it under your fingers, try tapping your feet while playing! see website #3.
