I confess I haven't done the calculations, but I wager that if you draw a straightish line between Buxton, Ore., and London, you might land in Queens, N.Y. At least, that's the accent Oliver has decided to synthesize based on his dual linguistic inheritance.
Dog=Dawg. Bird=Boid. Jupiter=Jew-pidour.
Who knows where this comes from. He was born in New York, but on the West Side. Maybe it was the chemical waft from Newark that did it and this is really a homage to the Sopranos. Also, K and I did watch and awful lot of Law & Order when we lived in Manhattan. Poor child. Add that to the faux south where he currently lives and he's going to develop an accent unrecognizable to modern anthropology.
Perhaps it won't matter, as long as the bird doesn't chase the dog around Jupiter.
