Andrew lived to see the book published and to get to know that people really enjoyed it! That was a great time in the community, he used to visit #wingnut to talk about it. Just a really nice guy, and whip smart.
You are probably remembering that Baen put the wrong name on the book cover when it was printed. They apologized and corrected it in the marketing but it was too late to redo the actual physical covers. It was probably just a big accident but because William Keith was a much more famous writer there was always that suggestion that maybe they did it on purpose.
