In 1964/1965:
“Paul Simon sang at the Peanuts a few times, his sweet, earnest voice and American accent seducing his listeners into rapt attention. I remember ‘Scarborough Fair‘ and ‘Hello darkness my old friend’ in particular, both specially coined for us in London, or so it seemed. He also sang at the folk club at the Railway Inn, in Brentwood, Essex, run by Dave McCausland and at the White Swan in Romford’s marketplace, which was run by Vince J. Docherty. I visited both of these on occasion, and knew many of the regulars well -– which included one Kathy Chitty, who sat behind the table at the door of the Brentwood club, a shy elf-girl taking admission money. Paul and Kathy fell in love, as is very well known. He would board the train from Liverpool Street after Peanuts sessions to get homeward bound back to Brentwood, where he lived with the McCausland family for a few months. It was the same one I took to return to Romford, which is on the way.”
