In a couple of weeks, the Roundhouse (London, UK) will host a 3-day Zappa festival.
November 5 -> 7, that is.
The Roundhouse newsletter mentions this, of course, but also adds info on a Sky Arts tv-special...
"Celebrate the life and music of Frank Zappa at our three-day festival that includes Zappa Plays Zappa and The Mighty Boosh Band all in association with our media partner, Sky Arts, giving you exclusive behind the scenes access to the festival. Look out for the documentary showing on Sky Arts 1 HD and at sky.com/arts this December. "
