Oh boy, did it:
Mistress Teleri Talgellawg>/b>
One hour of instruction in research and documentation, an hour of instruction on Anglo-Saxon performance, or an hour of musical entertainment (vocal and/or harp), winner's choice.
The problem, of course, is that I am not Mistress Teleri Talgellawg, but rather only Lady Teleri the Well-Prepared.
I have sent correspondence to his Majesty, who is coordinating the site, so that Mistress Teleri does not unexpectedly find herself asked to provide a harp concert. I don't even know if she plays!
