Howard, that was sold off and is now the storage building for the DODS theatre luvvies and it's their baskets, pop in there for a bit of relief and you could be in for a surprise.
Reminds me of something that happened when I was at Pfizer, we were always being moved around and rooms changed in those days. A colleague came out of a meeting in a building where he used to work in need of call of nature, walked through the door of the gents and had got his flies open before he realised it had been converted to an office and several typists were looking at him quite alarmed
