Nice to see people remember the Windmill Bar.
As correctly mentioned above, before that it was called "The Shoulder Of Mutton"
I can also confirm, that the Windmill Bar fun pub officially opened on October 26th 1981
I was both the original DJ and Assistant Manager. Had some great times there met some great people, saw some great acts.
Once it became "The Rocket" and "Thingy Ma Jigs", I had nothing to do with it, as I'd left by then so can't help on any info during that time.
Cheers
