You got there first with details of Dave, Jon. (Dave and I have been associating and doing some work together over the last few years). Is there anything that I can help you with at all Conrad? (I'm none too sure whether you have a general interest or a particularly specific enquiry relating to Lucy or John.)
While carrying out research on the Broadwood diaries and papers Dave and I had the pleasure of bumping into Alan Gibbs, a classical musical specialist with a great interest in Holst, who has also been carrying out extensive research on Lucy with a view to producing a biography of her based more on the classical side of her life.I've not been in contact with him lately, so have no idea how close or otherwise he may be to producing his own book on her.
