Alan Lomax talked about it, didn't he?   I found this article online which looks like it's from the Canadian Journal for Trad Music perhaps.

Of course, for those of us 'of a certain age' growing up in the 1960s in Canada we were probably all heavily influenced by Maritime music due to Don Messer's programmes. I've even met people from Texas who remember the shows (didn't know they reached that far)! It certainly gave us a common repertoire.
