Good post Ste.
You're right about the irrelevance of whether a tune was played in the 70s, well known to us or rare.. to the younger people the music is all relatively new.
The type of venue you mention will begat a new, almost seperate, "scene" IMO.. one that will not attract to many of the seniors who atend now.
Smart, city centre venues with no strict rules on what can be played.. soul, funk, R&B, Jamaican, house all in the same room. Events where the word northern is absent; where there is no anorak mentality, no " ns etiquette" and no pissing contests about who played what first.. bit like the scene in Europe really.
These people are not going to go to village halls, miners welfare clubs and the like.. that will be the last refuge of the current elite, those who want to keep it "underground".
I was interested to read in another post that Stoke was "full" of youngsters: How full? 15? 20?
