Ian, I think The Mecca beat Wigan hands down in those two or three years you are on about.
Yes, I went to both of them at the time, and had some great nights at both.
I agree after 75, Wigan the music was dire and I stopped going.
As for as music goes it was the last years when Wigan was unbeatable, that's when I started going again.
I never did the Friday Oldies nights, but I never liked Mr M's, I always wanted to hear new stuff when I went out.
Back to the orig question, most of the older lads that I knew back when Wigan opened did not like it and quite alot just dropped off the scene.
So to them soul did die when Wigan opened, but to me and people my age, Wigan was just a club that was right time and right place, just like the long list of clubs big and small. That all of us have enjoyed down the years.
I think the soul scene would still be here with or without Wigan, even if it was on a smaller scale.
Yours Dave (old git) Taylor.
