Seems to be a couple of verses missing from that song...

Were you ever in Ottawa?
Strangest place I ever saw
There the mounties keep the law
Riding on a donkey.

Were you ever in Ile St. Jean?
Or the Ile D'Orleans?
There the folks drink whiskey blanc
Riding on a donkey

Mirramashee is just a phonetic spelling of Miramichi. That's exactly how Miramichi is pronounced.
