I used to play the tutophone in my primary school band - but nothing came naturally to it - other than your basic 'toot'.

'Gotten' is certainly common, if not standard, in Canadian English. Our grammatical guides always insist that it is archaic, at best, and to be tolerated only in that spirit in which one tolerates a peculiar old relative, but in actuality, it is very widely used. By me, anyway. Maybe Charmion will chime in.
