" a front for lavish entertainment in Swallow Street, Piccadilly Circus" sounds extremely interesting and juicy!"
While not imputing any connection what so ever I came across this article in the Evening Standard on "Mr Soho", when I googled "Swallow Street, which now has a restaurant called "Gaucho".
http://www.standard.co.uk/news/is-it-all-over-for-mr-soho-6979938.htmlI am sure any connection is just fanciful unfounded imagination,, but there were quite a few "louche" establishments in that area, dating back many centuries....
More to the point, the Canning Town Glass Works and the Rockware factory at Greenford, near Harrow, were the last two major London Glass Works.
the late Dr David Watts "Glass making in London" privately printed book is a very comprehensive history. I think we still have a few copies left in our shop as it may already be out of print!
