John, the pub was the "Richard" I (often known as "The Tolly" - the brewery who owned it before Youngs) which is in Royal Hill - where the Lachenal Concertina firm was based.

Are you sure you mean "The Railway Tavern" at Catford ? The Catford Folk Club was for many years at "The Rising Sun" - where your mates "Legacy" were a resident group. I ran a club at "The Railway Tavern" Blackheath, even nearer to Bert, and he was a fairly regular guest.
