I am Joy Masefield's son.
My mother, who died a few years ago in her nineties, wrote the words for her Son et Lumiere production at Towersey parish church in the late 1960s. She was very pleased that Roy Bailey and Leon Rosselson became involved in her various productions. (Basically she taught herself how to write folk songs to highlight key scenes in the storyline. I remember her listening to Ewan McColl and various Irish ballads initially. She always had an interest in the theatre, writing scripts, acting and producing prolifically and successfully at amateur level.) She then formed a company with Colin Saunders and Giles Brandreth - Archway Productions - which put on professional son et lumieres at Temple Newsam House near Leeds and the Greenwich Observatory (the latter for Oxfam, starring John Gielgud, Alec Guinness, Claire Bloom and others).
I love the Cobweb of Dreams - it was the finale at Towersey, and I helped do the lighting and sound every night for the two week run; many happy memories. My mother was so pleased when I told her some years ago that at least one of her songs was played professionally.
I have recordings of all the soundtracks of the son et lumieres if anyone is interested, and one or two 45 vinyl records of the Towersey and Greenwich songs.
