"East Lon'n into Essex"

Not a fan of Billy Bragg I'd wager then RB? I've nothing against it myself, though the excessively affected adoption of 'mockney' by middle-class kids from well-to-do Essex villages irritated me growing up "Awrih' BABES?!". It was Eastenders that caused it of course. By which I don't mean the actual Eastenders who came to Essex, but well spoken actors from drama-school pretending to be Eastenders on telly.
