Here are a few more names for your lists that I had in my notes and files that I thought might be of interest. (I searched through this thread and didn't notice these names - with the exception of one.)
Nathan East - bass player for Eric Clapton (and studio/live performance bass artist for many others)
Lou Taylor Pucci - actor "Personal Velocity," "Chumscrubber," "Empire Falls" Tannen's Camp alumni
Adrien Brody - (already mentioned) "the Pianist," "King Kong" was another Tannen's Camp alumni
Ben Curtis - actor, the former "dude, you're gettin a Dell" spokesperson, Tannen's Camp alumni
Robin Leach - best known for "Lifestyles of Rich and Famous" show
Norman Schwarzkopf - Retired general, former US Gulf War commander
Lee Majors - actor, best known from 1970's "Six Million Dollar Man" TV series
Wil Wheaton - actor, from "Star Trek The Next Generation," "Stand By Me," etc
Derek Hughes - actor, mainly known for vast TV commercial work, Tannen's Camp counselor
Vinny Testerverde - the New York Jets
Walter "Killer" Kowalski - former pro-wrestler, and trainer
Bob Fitch - known by magicians for his directorial skills, "topit" work, "hold-out" work, and private workshops, well-known Broadway performer.
Nicholas mentioned O.J. Simpson and Tony Randall on Circus of the Stars. Other episodes (as I remember) featured actress Delta Burke doing the multiplying bottles with Merv Griffin as her foil, actor Glen Ford doing a "dove" and duck act with Pamela Fyre as his assistant (I believe she worked with Tim Kole at Knott's Berry Farm as "Fyre & Kole" in late 80's in "Spellbound"), actor Pat Morita doing the Anderson tear, and a sub-trunk with a combination "safe." Wow, the memories. I don't believe anyone from these "circus" acts persued an interest in magic.
Happy New Year, all!
