I saw Bob Gibson perform at the Finjan, early sixties. More info as i search the musty corridors of memory. I just digitized his LP, which I bought either there or just after. His repertoire at the Finjan was pretty much the same as on the LP.

Saw Shimon Ash & spouse(?) play too at their own club a few times.

For years my route to work took me up Victoria (in Snowden area) and I could remember that you had to go down a back alley and up some stairs to find the place, but exactly where...???
