Makes sense to me. Her speech was distorted by the stroke and so she accidently sounds cockney. It's a coincidence. The article mentions the Norwegian girl who sounded German after her accident. When I lived in North Georgia USA, I used to run into people with British accents. They were from the Southern Appalachian mountains. The thing is that they and their ancestors had lived up there with other decendants of Britian rather isolated for a couple of hundred years and the accent was not diluted by other accents from other ethnic groups.
Let's hope it's better than Dick-Van-Dyke's accent in Mary Poppins !
This makes me smile. That was a bad accent. Goofy really. But it's funny in reverse, too. I used to get a kick out of Benny Hill trying to portray southern or western USA Americans. He basically sounded British with a drawl or twang. You may not share my opinion of Benny Hill. I thought him adorable. I like Monty Python the best, though. When they dress in drag and portray British biddies it's just maybe the funniest thing on Earth. I liked it when the Pythons portrayed ladies reinacting the bombing of Pearl Harbor.
Since you visited Florida, I wonder what you thought of the southern accents there.
