Yes went to all of them, and even one night when it wasn't on. Shocking but a load of us came up from Kent, only to find it empty. So we had to get some staff train back to St Pancras at about 3 am. There were several of them promoted by Ken Cox EASC I seem to recall. Always a big crowd there, most memorable ones for me was when Nev Wherry was DJing but best of all when Sam was on playing all the big Wigan 70's - Love committee cover up, Top Cat etc. It go me to go back to Wigan after a two year absence. Got my Ronnie McNeir there for £10 as well. So a good event in my books.
Did a write up in The Northern Line (forerunner to Blackbeat) will try and find it. 1980 I think?
