Just to try and clarify things, I was writing about The Ballads and Blues Club where Ewan and Peggy were virtually resident at the time. It would have been there probably that Peggy heard Long John.
I was not referring to The Singers Club which Ewan and Peggy formed along with Bruce Dunnett at a later date. I have pointed out on earlier threads that it was at the Ballads and Blues Club where Ewan started all the bit about singing songs of your own country. He did not consult us the paying audience. He may have done so at his own club but as my visits there were very rare I cannot say.
I would have been very surprised indeed if John had appeared at the Singers Club. He never did while I was handling his bookings.

As a matter of interst Jim Were you around the London folk scene during the fifties? It didn't just start with The Singers Club you know.
