Someone different for everybody I should imagine, and as well as that it would be silly to put that onus/accolade on just one person, so we are just being asked for our own personal preferences I suppose.

In the UK I would propose Harry Cox, using the traditional sources,
Norma Waterson always my biggest and initial influence, and of the new youngsters I don't think Cohen Brathwaite Kilcoyne can be bettered.
