Georgian - I had the same sort of schooling - my rural accent was literally beaten out of me. Singing in the church choir helped to dampen it down, enunciating properly for the (mostly deaf!) congregation. I still have moments though when it pops out, usually when I've been visiting relatives in Dorset or spoken to one of the South-West offices on the phone.

I'm pathetic at working out accents though... I have to have the subtitles on for any TV show produced north of Shrewsbury.
