Funny also I moved to USA ~20 years ago and you lose the Italian, you don't remember words etc. but you'll never lose your dialect, it just comes natural because that's how you grew up instead of what you learned growing up and from school, Tuscan people have it easier because the language comes from their dialect, Dante etc.
And to add, I wouldn't click that link if you paid me lol, I hate the Barese... ok I clicked, funny stuff.
