Tori Amos Is Writing a Musical

My favorite redhead Tori Amos is writing a musical called, so far, TBA, and it will be shown at London's National Theatre in April of 2012. That's all we know. What will it be about? What will it be called? Can it be, like, an adaptation of a Muriel Spark book, or the St. Trinian's series (which has since been made into a couple of quite fun films with Colin Firth in them, and whose setting is a bit like a choirgirl hotel)? Or a musical-length version of the song "Tear In Your Hand"? In the meantime, here is some Tori Amos in HD on the Internet!
