I'm sure this is just a coincidence, but I can't help finding it horrifically funny that they used the name "Paul Campbell." Paul Campbell was a pseudonym used by the Weavers for their writing, and of course, the Weavers played the music (by then 30 to 40 years old), that I listened to in my teen years and which put me hopelessly out of touch with my generation.
