Re: Brummie
The accent in Lichfield, or at least south Staffordshire, is not exactly Brummie
Likewise Leicester (which is not unadjacent to Brumagen[1]) has an accent that manages to veer between a soft Yorkshire and a middling-Brummie.
Most disconcerting.
[1] Where I was actually born. Neither of my parents had Brummie accents and we managed to move to Norf Lunnon before I really had much contact with the local accent. Apparently I have a pretty neutral accnt unless I get very enthusiastic about something - when traces of Barnet creep in..
