I was thinking just the other day that his time left couldn't be that ample, owing to his age.
We who enjoy and indeed love the works of his father, must recognize our unpayable debt to this man. Instead of exploiting his name and position for his own enrichment, he devoted himself to research and editorial work, bringing to light unfinished and prototype materiel that supplements the original publications in a marvelous way.
Thank you, sir. "Manwe keep you under the One, and send fair wind to your sails".
