San Diego Filk Fandom (in it's current incarnation-unknown if organized filking existed before), got started in the year 1980, by Barney Evans and Rilla Heslin.
Association of filkers living mostly in Southern Ontario, with a little a few coming from as far as Ottawa in Eastern Ontario and occasional special guests.
Filk music is perhaps one of the most underground music styles because it's almost impossible to find. Coming from the world of science fiction and fantasy fandom, the music can only be found, for sale or live, at Science Fiction conventions, a handful of stores, and here on the Internet.
Filksongs are folksongs by or about science fiction fans or writers. Or, more loosely, any song which is either to the tune of another song or in any way even vaguely related to sf or fantasy or fandom. The term "filk" arose in the 1950's, as a typo by Lee Jacobs in the title of an essay. That 'zine never got published, but the term "filk" got passed around by fans, and the name stuck. The rest is history.
List of Filks some in text form others in MIDI format. Also available is a description of what filk music is and a collection of links to other filk sites on the web.
