At the end of the day, you have to put things into perspective & The Casino went stratospheric, although, yeah still a sub-culture, it was virtually mainstream, in a way like no other soul venue has ever been or ever will be in future, nothing today could get anywhere near touching it for popularity and interest, a couple of thousand people EVERY single Saturday night and a Friday night once a month too.
So, inevitably this brought a whole new way of thinking & things changed rapidly, records would be broke, be popular, get pressed, and fade away within months, the turnover of new tunes was immense and new people were coming onto the scene on a weekly basis too.
Also, you had bandits like Simon S, sponsoring some of the dj's for their own promotional ends thens it's no wonder some of pop broke though.
I'm might get slated for saying this this is my opinion, but, you did actually have what you might coin 'lads' tunes & 'girls's tunes, and in my opinion some of the more poppy 'girls' were responsible for a lot of the pop, not saying all, but just a higher percentage at that time & there was a massive influx a 'girls' jumping on the bandwagon & onto the scene at that time that were obviously being catered for, or targeted. (I'm thinking Muriel Grey & Lorraine Silver).
But that was the way it was, and the choice of sounds was so varied, there was something for everyone & it was just a case of 'well I hate that' but something good was always two minutes away.
All that said, the venue sported most of the best quality sounds ever introduced to the scene too & shouldn't be lampooned solely for that pop period exclusively.
