My grandfather was from Downeast. He sure didn't sound like this at all. His accent was thicker than this. A few of these people sound kinda like some of my relatives but not a ton. It is not easy to talk like my gramps did but I can at times because I was around him alot. Everyone knows it's not Bingo it's Beano bub.
...and then there's "canadian maine", nova scotia. You could swap half the populations from each place, dump 'em in the other one, nobody would know the difference.
