Hello again,Eric the Viking,
A correction to my earlier post (the old memory gets a bit shaky). Keith Willson used to do backing sometimes for Raggy Farmer (on, I think, the double bass) at the Thurlow Arms. I remember him lugging that double bass - called Fred - on the bus to the gigs. Keith used to play solo at the Half Moon in Herne Hill in the 1970s - I did a few spots there myself. Others from that scene were Rodney, and Ivan (who used to have a sticker on his guitar saying "You live the life you choose"). It should also have been the Brockley Brothers.
