Thanks for the suggestions, I'll check them out.
JrCramer - Thanks!
Tokkemon - I've written an oratorio with a fictional libretto (by me) based on bushfire stories from around Australia. So I'm interested in seeing how other contemporary composers have dealt with fictional, secular oratorio libretti, and how they've still managed to maintain the 'contemplative' nature of oratorio using those subjects. Thanks for the Monty Python suggestion too, I'll check it out!
