The photo is of the excellent Dr William Lovelock standing outside Trinity College London. That’s where I did my LTCL when I was a student.
All the exercises from this book are complete but they are in manuscript. I will put them into Dorico bit by bit and make any improvements as I go.
When Chapter 2 is ifinished (Chaper 1 is a pep talk, and already available to see on this site), I will upload it and then most likely make mockup recordings using Dominus Pro Choir.
So far, I don’t know what to do about the Latin words in Dominus, probably use use vowels as otherwise it’ll take forever.
