I had the great pleasure of seeing Guy at the Ballads and Blues Club at The Princess Louise in London around 1957/58 and have a photograph of him in duet with Peggy Seeger. Also saw him many years later at the Singer's Club in the basement of a block of council flats in Islington.
Not such pleasant surroundings but Guy was as entertaining as ever. He was certainly one of the people who helped to get the folk scare started over here.
