Accordion is still very popular in the province of Newfoundland where the accordion is referred to as the "cardeen", especially by people from"around the bay" (from the more remote out-ports).
I remember one guy telling me, tongue-in-cheek of course, that no Newfie "cardeen" player was worth his salt if he couldn't play the Minute Waltz in 59 seconds or less.
They also called the accordion (piano or button) "the squeeze".
I was fortunate enough, when I lived in St.John's Newfoundland, to play piano with some pretty awesome button accordion players, including a few CBC Radio recordings nearly 20 years ago,(can't find them) with a lovely lady, Minnie White, who was playing well into her 80's.
