I should know this but... how did Joe convert what was a street into a 'bar'. Was it a right of way, did he have planning, did he buy up both sides of the street, was it a 'scaffold and just do it' or a more gentle bit at a time development.
Shutting a street must have been a fairly big deal.
Joe Robertson ran it when the City Vaults was on one side and Brahms & Liszt on the other, but I think he had sold them before the lane was closed off.
It was a great shame that ever happened, because (as I remember thinking at the time in the 1980s) the architecture all the way down both sides of that lane was VERY good for such a narrow 'back lane' type of street.
