Good luck Dave - look forward to hearing how it goes.
The problem with identification terminology is not that people have reached a consensus, but many people have decided that it is not necessary, but have reached the Alice Through the Looking Glass decision that "words mean what I decide them to mean" - fine if that's the garden you live in - no good to those who decide to peep over the wall.
Mention the term 'definition' and out comes the crucifix and garlic.
I've said it before but.... I stopped going to most clubs (from a four/five-times-a-week addict) simply because I wanted the freedom to choose what I listened to when I wanted to listen to it.
I love classical music (in most of its definitions) but I'd be pissed off to turn up to an orchestral concert to be met with a Bix Beiderbeck (who I also love) soundalike - if that happened a couple of times the Liverpool Philharmonic Hall would very soon end up with no punters.   
I remain convinced that this is the cause of the decline in the folk scene as I experienced it.

Agree entirely - would love to expand when I have more time - hopefully it will pee with rain this afternoon so I can escape from the garden
