For those who weren't aware, the world-renown Monty Python was first introduced to the United States in 1975 by my local PBS affiliate, KERA in Dallas. I had nothing to do with it, as I was only 1 year old at the time, but I'm proud nonetheless.
When I was about 13, my best friend introduced me to "The Holy Grail." Again, this ran on KERA. They used to show it fairly often, in fact. As I remember, they also used to run "Flying Circus" every weekend. My friend and I would stay up many late nights keeping my parents awake with our badly stifled laughter. Unfortunately, I haven't seen them run it for several years now.
Anyway, shortly after KERA starting airing "Flying Circus," they invited four members of Monty Python into the studio for an interview. A portion of that interview, saved by an engineer, was recently uncovered. It hadn't been seen in more than 30 years.
