Similar thing here. The "club" when I was a member there consisted of perhaps 12 people that played accordion, 3 to 4 of which played. They consist entirely of people 70+ years old, including the non-playing members, of which there are many more.
Musical interests entirely consist of 3 genres, French Coureur du Bois, spoon to knee folk songs, country music horribly translated and over and over quite badly played and a few VERY specific and often repeated Italian songs. There is absolutely zero interest or tolerance for anything else. Basically if it is not a narrow focused group of Franco-Italian, it is not heard and they let you feel that strongly. When I played there, I played Beer Barrel Polka... NOT ONE person knew what it was.
Meetings start on a weekday at 4pm and end around 7:30 because by then 2/3rd of the audience is falling asleep. The president of the club (at the time I was there) is the owner of the biggest (and only) accordion store in Montreal... and he plays well, except that his first love is saxophone and that is what he brings to the monthly meetings.
It is less about accordion music and more about keeping the folks from the seniors care center happy. I managed to stay a whole 3 months before I left. When I saw the yearly calendar for the coming year at the annual Christmas party and for October, I was hoping to see "October fest" and saw a (repeated for the 6th time) "French Country Night", I knew this place was not for me.
