The show is "The Knight of the Burning Pestle", the only full-length non-Shakespeare period scripted play that Carolingia has ever put on. The production was directed by Alexx and produced by me, and grew out of our Elizabethan Theater class in college. The professor asserted that KotBP was the funniest play ever written, which kind of mystified us -- when you just read it on paper, that's not at all obvious. Eventually, Alexx threw himself into it, spent a fair while understanding the language and jokes well enough to grok *why* it is so funny, and wound up figuring out how to produce it properly.
It's quite a bit of fun, and much more modern than you might think. The fourth wall gets not just broken but stomped all over (within the first minute of the play), as the play gets warped and reshaped by the audience. It involves monstrous barbers, a magnificently ridiculous death soliloquy, a gratuitous maypole dance, the first known instance of the arrow-through-the-head gag, and the only Grocer Errant in theatrical history.
The recording is homebrew, and I'll warn that the sound quality isn't always the best, but it's reasonably followable. Recommended, both as a good play and as a neat piece of Baronial history -- y'all come by...
