You're right, Jim Lad.
Avrosimone, don't mind us cantankerous old buggers. OK some of us wanted greater definition in the question, but don't let that stop you from being active on the board. And here are four names by way of apology:

Mick West of Glasgow (trad Scottish and Irish)
Ian Giles of Oxford (all trad, medieval and anything goes)
Ian Woods of Oxford (trad English plus self-penned in the trad style)
Graham Metcalfe (trad English, strong Yorkshire emphasis)
