There's a sort of middle-England, fairly nasal, not-quite-south but vaguely norf of Landon accent, veering slightly Norfolkwards, that some English folkies adopt to make them sound sort of villagey-rusticky-I'm-a-yokel-shagging-a-maid-in-the-corn-afore-a-sheep-shearing-or-a-begging-I-will-go. It's very affected and has put millions off taking folk-song seriously, almost as much as finger-in-ear syndrome has. No names, no flames. Mind you, people who sing in their natural accent can grate as well. I always thought Shirley Collins carried it off wonderfully in her own natural voice, whereas I can't listen for more than a minute with buttocks unclenched to Ms Rusby's Yorkshire twang. I don't know what it is. Maybe I'll stick to instrumental.
