Sounds like a Worzel, so could be Norfolk (it's odd how similar Norfolk and the South West accents are)
I've asked the Carrot heads and Worzels the reason for that a couple of times but they said that to them, they are entirely different. It is odd though considering there's a large swathe of middle England separating the two.
strange ain't it, I have a photo of one person from Somerset and one from Norwich, very hard to spot the difference please log in to view this image
