The song "From House to House" has an interesting history behind it, talesin, that might interest you and some others. Harold King was its writer. He wrote it while imprisoned in China for being a Witness missionary when he was in solitary confinement. Harold King was not your average Witness but quite an intelligent man. He had studied mathematics and while in solitary confinement he created a routine to keep himself sane. He would pretend to spend the day in field service. He had a "magazine route", "Bible studies", people who would argue and/or debate with him, and even "not-at-homes". I thought that was amazing when his story was related to me. When the communist authorities realized they weren't going to "reeducate" him, he was released and expelled from the country. He's been dead for years now, but that particular kingdom song is still in the Witness musical repertoire.
