I don't know whether anyone's posted about these before, or is a
bittorrent enthusiast, but I've found the 1988 PBS 6 part series of
interviews between Joseph Campbell and (the excellent) Bill Moyers,
shot at George Lucas' Skywalker Ranch, with gratuitous Star Wars
references.
Just watched the first one, and thought that I ought to let you guys know.
The torrent is here;

enjoy!
