Not been on line for a while so this thread is new to me, so forgive me if I bring it back on topic (ish)
I don't see a North - South distinction at all its more local than that. Even if you look at the various nights at Sheridens they are all different yet (in the main) well attended. Lifeline to me is the tops but it appears that people who want that type of music policy are willing to (have to) travel further to get it. You can go to an 'oldies venue' almost anywhere yet '6ts newies / upfront venues' don't work in many places.
Where they do work they get and following the average distance travelled to get to them is massive compared to the distances travelled to get to most 'oldies events'. Consequently people have travelled from North and South (and the Midlands) usually
Where I percieve a slight difference between North and South is in the age profile with the South being slightly younger. Age is an important factor those too young to have gone to Wigan do not appear to be wedded to the 'Wigan Oldie' because it is less about nostalgia for them. The same can be said about those who never left the scene in the 80's be they from the North or the South perhaps people like me have been in the 'newies camp' from the days of the Casino but where I live makes little difference to that other than how far I need to travel to find a venue with the right policy for me.
In short I'm glad I live in the North for all sorts of reasons but wish 100 club, Plinston, Sheridans, Wilton, Steam were closer to Blackpool
