A few memories on this thread ... Rising Sun in Catford was my first folk club when I moved to London in 1974 - I had digs in Lewisham, so it was fairly easy to get there. Bonnie and I teamed up with some others to share a house after that.
The Enterprise - ah, yes - and the Florence ....We used the Enterprise for a launch party for the Anonyma album "Burnt Feathers" in 1986 and it was already heading up market then.
Someone mentioned the Sols Arms - that came later, in the 80s, and was a good venue.
But Dingles (at the Adams Arms) was another favourite haunt.
