I had a surprise telephone call tonight from a friend and former neighbour who has been reading this thread with interest.
He confirmed that there was a disco/nightclub in Bay View Road Colwyn Bay.
It was located in the Green Lawns Hotel and to get to it you went up the steps in the hotel then through the reception hall and the disco/nightclub was in the back of the building.
He said that it didn't operate for long and was open sometime between the late 1970's and mid 1980's, He remembered it well as the club served drinks long after the other local pubs had closed. Z**
