produced by Terence Tiller, but had an afterlife as an extended choral work for concert performance. Another choral piece (and the only extended work of hers to have been commercially recorded) is An English Day Book, a 20-minute sequence of sacred and profane poetry settings relating to different times of the day and year. It includes a setting of Sweet Suffolk Owl by Thomas Vautor that has achieved separate popularity. The Concertino da camera on a Theme of Martin Peerson (1957) is a significant example of her music for chamber ensembles, and has been recorded. A Swiss radio broadcast of her 1960 Trio for flute, viola and harp can be heard on YouTube, and a new recording of the Trio by the Korros Ensemble was released in 2021. A six-minute work for string orchestra, Blackberry Fold: Requiem for a Dog, received its first broadcast in February 1976. Her carols, especially "Jesus Christ the Apple Tree" (1967), remain widely performed. In total there are over 300 compositions, some still to be discovered. Poston's extensive archives are now housed at the Hertfordshire Archives and Local Studies in Hertford. Writing and editing In addition to composing, Poston was an academic, writer and editor. In 1947 she created a five-part lecture series on Peter Warlock for the BBC. Much later, she defended his reputation in a very personal broadcast talk. She wrote articles and programme notes for the Arts Council of Great Britain and was the editor of a number of vocal music anthologies, including The Children's Song Book (1961), which was described as "a little autobiography, reflecting her own delight in songs since the earliest she remembers from the age of two". The book contains five of her own original settings, including a short song version of Jesus Christ the Apple Tree that was the germ of her famous choral piece, fully realised six years later. There were also three Penguin collections – The Penguin Book of Christmas Carols (two volumes, 1965 and 1971), and (with Alan Lomax) The Penguin Book of American Folksongs (1964) – as well as (with David Holbrook) The Cambridge Hymnal (1970). Later career Poston was the president of the Society of Women Musicians 1955–61. She continued to live at Rooks Nest House until her death at the age of 81 in 1987. A catalogue of her works by her friend Dr John Alabaster published in 2018 lists some
