Golly gosh... it was long ago when a few radio stations in listening distance of the various places I resided would air the King Biscuit Flour Hour. I do not remember any mention of quad though that term was not on my "radar" at the time. I was aware of quad but its expense and having to haul stuff around so often during frequent moves led to my sticking to stereo until the early 1990s. That was when I saw the Masterworks brand basic quad receiver in the thrift store and sighting it the memories of quad returned and curiosity led to my buying it and the quest began.
Found this:
"The concerts were usually recorded with a mobile recording truck, then mixed and edited for broadcast on the show within a few weeks. In the 1970s, the show was sent to participating radio stations on reel-to-reel tape. Some shows were recorded and mixed in both stereo and quadraphonic. In 1980, D.I.R. began using the LP format, producing the show on a three-sided, two record set. The first show on compact disc was a live retrospective of the Rolling Stones broadcast on September 27, 1987. By the year 2000, King Biscuit was using CD-R media to distribute the show. These tapes, records or compact discs were accompanied by a cue sheet which gave the disc jockey a written guideline of the content and length of each segment of the program."

Anybody ever see a quad King Biscuit Flour Hour tape or LP? I wonder if there are any floating around out there? Anybody ever hear a quad broadcast of the show?
Another little piece of the quad era that was not recorded well for history.
