James Percival's BA thesis was about Delia's music and his 2013 Masters thesis was Delia Derbyshire's Creative Process. He was then "Musicologist, Delia Derbyshire Archive" at Manchester University and indexed the Attic Tapes and Attic Papers.
He has also written a paper Review of "Special Sound: The Creation and Legacy of the BBC Radiophonic Workshop" and given a talk "Beyond 'Doctor Who': (re)discoveries from Delia Derbyshire's tape archive" and was a panel member at the first Delia Derbyshire Day event in 2013.
“There was a perception by [BBC] musicians at the time that the BBC Radiophonic workshop would put them out of business. Now, THAT got her back up.”
