CAJUN ACCORDION DISCUSSION GROUP
Dewey also does a B part, different than Amede or Bois Sec's B part, on one of the New York recordings.
We did that one for Jamey's Tune of the Month project. My trial had a second part too. Website #2. I don't even remember where I got that from.
I would say the turn Courtbouillion does is more of a variation. Same chord changes and everything.
