I also dislike the new voice. I'm sorry they replaced Dave Kelly. He did a much better job IMO.

And by the way...James Marsters (Spike from Buffy) was doing a North London accent he was taught by a guy he was doing a play with at the time. The London Guardian put his on the list of its most convincing British accents done by non-Brits a few years back. (Dick Van Dyke's Bert from Mary Poppins was on the list of worst).
