I just stumbled across this thread. I used to work for Plessey and in early 1970 I was at Beeston for a three month course.
Our first b&b was pleasant but boring so my colleague Ted Murphy, discovered The Musters.
We had a very pleasant stay there! We had the room over the bar and our shared bathroom/toilet was used by customers "in the know".
I remember Penny Wise who was sort of friendly with the bar girls, whose names escape me at the moment.
I do remember that they bought a battered old ambulance that they christened Annabel and eventually drove it to Greece
