Last month (June 2019), I took part in a two-day performance workshop organised by Joseph W. Mason and attended by various other people I’ve worked with over the past decade or so. I introduced and advised on performances of a song by Blondel de Nesle (people who have heard me sing will be happy to hear that I delegated that task to others far better qualified!).  Joe has written an excellent account of the entire event, obviating the need for me to do so here. I refer you enthusiastically to his blogpost, which has embedded audio-visual footage of the public concert that resulted. Enjoy!
