A good point, Don. What is the difference between a dialect and a language (apart from the language having a bigger army)?

Funnily enough, I have Polish students of English who speak English with German or French accents because that is their primary second language.

I just put this question to my wife, who is Polish and learns traditional songs from Poland, Belorussia and Ukraine (as well as other places)and studies/practices the regional singing techniques as well.

She was puzzled by the question and then replied that if she knows th technique and the style of singing then she tries to sing it as they do (with accent/pronunciation) BUT she stressed that "it shouldn't just be a cheap copy, you have to know what it is your singing and doing".
