How's this. filk is a collection of science fiction/fantasy/SCA parody songs. From the sound of it, this "Dueling Bards" might fit right in. Take a popular tune and re-write its lyrics (or in this case, write a complete set of them) to tell some usually humorous, often bawdy song about your science fiction/fantasy/SCA hero.

I *believe* that they started out at science fiction conventions. (Since SCA started out at a sci fi con, that would certainly make sense of where THEY got 'em.) But they're merely a specific genre of parody.

That said, there are actually a handful of songs that're generally considered filk that might well be ALSO considered good music.
