I give, for what its worth, another story told to me by the person to whom it apparently happened. In the early 1960s he was being employed to examine the archives of a theatre in Lincolnshire, UK which was scheduled for demolition. Most of the fixtures and fittings had already been removed - including the theatre's electrical generator. He had only oil lamps for illumination. One dark evening he ran out of cigarettes and made his way with the help of a torch from the dressing room area, across the stage and into the auditorium. As he approached the baize doors which led through to the foyer (which was reached down a flight of steps), he noticed a light shining under the doors. Thinking the night watchman was probably there, he switched of his torch and went through the doors. Ahead of him the foyer was completely lit up. A long coconut mat ran down the stairs in front of him, across the parquet floor and up a further flight of steps which led to the exit. In the ticket office, which was empty, he saw tickets and what appeared to be programmes piled up. There were posters and pictures on the walls and, on either side of the matting, cane/bamboo chairs and tables on which were spread magazines.
According to his story he walked the full length of the foyer, turned, walked back again, turned and walked through a third time - finally pushing open the front door and emerging into the street. He then took to his heels and spent the night on a friend's sofa.
On visiting the theatre the following day, he found (as he knew he would) that the foyer was totally gutted and empty - no furniture, no posters, no ticket office, no parquet floor, only dusty floorboards. When he questioned the current owner of the theatre as to whether or not there had ever been a parquet floor in the foyer, he was told that there had been between 1922 and 1924. It had not been a success for one reason or another and had been replaced with polished floorboards.
I never had any particular reason to doubt the truthfulness of this person - and I must add that he did not take drugs and was abstemious with alcohol. Make of this what you will.
