My mom often repeated a rumor that Stephen King is a DF'd witness. I have read some of his memoir, searched through the e-book, and I can't find anything to suggest that.
Good call on Hank Marvin, @Tallon. You could add Larry Graham as well for slap bass.
The fact is: If you are a creative JW, your creativity is going to be stifled. You have to do all things for Jehovah. Can you write a book that portrays evil? Can you even have a single character get murdered? Can you ever do anything without Jehovah looking over your shoulder?
This is exactly why I had a few JW friends who are creative people who were considering pseudonyms. How terrible is that? "Yes, I'm afraid to use my real name, because I have this Zombie apocalypse story about a boy wizard, and it might get me separated from my family because we're in a cult."
