I listened to part two of the Robert Anton Wilson lecture rebroadcast on the Psychedelic Salon podcast (see my previous two posts) and found it worthwhile. The conspiracy stuff mostly covers familiar ground (although I don't remember hearing about the medieval black virgins before) but there are also two interesting question and answer sessions. The rest of the podcast (more than two hours) seems to be about Occupy Wall Street -- interesting, but I didn't have time to finish it.
One of my favorite SF writers, Jack Vance, wrote in his memoir that he gave up giving formal speeches and switched to simply getting up and answering all of the questions that were put to him. If there are any recordings of Wilson doing that, I'd love to hear it.
I should point out that there's also a podcast that apparently uses portions of "The Lost Studio Session" of RAW. I bought that album as soon as it came out, so I guess I don't need the podcast.
