Such a shame that the only "Magic of Fred Kaps" book out is the one you need those special red glasses to read. And he's been gone for over a generation now.
I hope Koornwinder book on his magic gets published before suits become as retro as spats, canes, smoking - before folks know enough about dragon/Phoenix coins to wonder about the symbolism and ... relegate Kaps to some mythical past when silver dollars were silver, people smoked, when Ken Brooke had a store and he was the guy with salt streaming out of his hands while the audiences was screaming for the Beatles to perform.
I feel it's a shame that we have such a delay between the display and the publication of such wonderful material. Especially when the person involved was, unlike Karl Germain, open to teaching what he showed.
IMHO there's little benefit in holding onto material - as it's your approach to performing and aesthetic choices which make all the difference to audiences. On the negative side, holding onto "A" makes it politically awkward to publish things which evolved from 'A' and have since been time/audience tested and are themselves of merit beyond mere derivitive works.
