Northshore, Massachusetts. With a few caveats accordions are welcome here. If it is appropriate to the song, if the player is at least halfway decent, if the instrument is in tune, then everyone seems to enjoy it. A mediocre guitar player won't be noticed but a mediocre accordion (or banjo or bodhran) can be a problem, hence the jokes. On the other hand, an accomplished European accordion player would leave us all in the dust. Fun to listen to but hard to play with.
