I was thinking about that too. When Northern arrived at our youth club in mid 74 courtesy of some 'big lads', some of us were into it like a shot and I'd attended my first nighter in 1975 - but what I remember most is that our disco, which was in a fair sized hall, would be rammed, and even the 'nerds' would be dancing to things like Get Out, I think it gave a lot of people confidence that they normally wouldn't have had, they'd just be sitting around the sides watching everyone else dance, but now they were all joining in. Most didn't stay with it, some did though, and we even had two succesful nighters at our youth club.
