"She is, at root, a plain Sussex women".

I agree that she is plural, but not that she's plain. Even in her 70s she's beautiful. And her lecturing voice is just like her singing voice.

Voices for coises; Shirley's voice is fine for telling a story or a lyrical ballad, and a voice that could drown out a trad jazz band is no good for that kind of stuff.

What puts me off is falseness: pseudo- mystic Seltic twilight echo machine (complete with low whistle), deep Lancashire doing nonspecific American, blokes with whisky beards who'd have yez believe they're from Dubalin when you know they're from Solihull. As for Anne Briggs's attempt at t'northern deealect, ecky thump lad.
