Here is an actual video of one of Harvey's "Rest of the Story."
In the '80s, Harvey was interviewed by some poor soul named Jimmy Carter (not the national disgrace of the same name):
Michelle Malkin has a guest blogger give an impression of Harvey's life. The writer is on-target: "Paul Harvey invented blogging; he just did his blogging on the radio."
I plan to add some Updates later.
UPDATE: I don't know where Harvey was, spiritually. An essay titled If I Were the Devil was circulated in Harvey's name, and he has read it, but Snopes can't verify whether he actually wrote it or not. It contains a lot of common sense and even some Biblical wisdom, but no overt Gospel. I imagine that religious remembrances of Harvey will include that dubiously-attributed essay, as well as the falsely-attributed essay on prayer, and another false "quotation" of Paul Harvey on Mel Gibson's The Passion.
Harvey read An Open Letter from God. From a Biblical perspective, it's utter rubbish, and I hope Harvey knew and believed better. It was actually written by Bo Lozoff, who was far from a Christian, and is subject of lurid reports.
