I finally got my copy of Malcolm MacDonald's opus on Havergal Brian - I've been after it for years. Secondhand hardbacks in good condition at a reasonable price. Just in time to go with the new Dutton release of #2 and #14.
I treasure the copies of each of the three volumes which Malcolm sent to me when they were published-free of charge but more importantly signed by him. Volume One is inscribed "To Colin-In Ancient Friendship". :) There is not often that I listen to one of the symphonies without the relevant volume to hand. No books on music that I have ever come across combine such detailed technical analysis with the incredible ability to enhance one's understanding and appreciation of the music through the vivid power of the writing. It undoubtedly helps that I knew him so well as a young man but when I read his descriptions I can still hear his voice. What a loss he was :( But he lives on through these and his other books :)
