The Firesign Theatre isn’t a theater at all. It’s the four-man comedy troupe of Phil Austin, Phil Proctor, Peter Bergman and David Ossman -- all of them born under astrological fire signs. They’ve been making theater of the mind for most of four decades, on radio, TV, film and in recordings. Now, they’ve come to All Things Considered, where their signature stream of comedy productions will air on special occasions – Halloween, Thanksgiving, Christmas – or no occasion at all.
