He was on a talk show back in the late 80's doing Snowstorm, Invasion of the Body Snatchers (one of the best presentations and handlings of Wild Card I've ever seen), and his ring and rope work (both with a large ring and a borrowed ring, ending with Ring Flight). The same show also featured David Roth, and I believe a couple other magicians (the copy I have was only part of the show, showing Roth and Samelson).
I can't remember the name of the show, it was Robert something (can't recall his last name, but he's a comedian and has a slight lisp) -- it was before my time, as it were, so I only know it from the tape.
My copy's in NJ right now, but if anyone's interested you can drop me an e-mail and I'll make a copy when I get back out east at the beginning of September. The same tape also has a couple of clips from Arsenio Hall with the Pendragons and Ed Alonzo, Joseph Gabriel on another talk show (I want to say Merv Griffin, but I can't remember offhand), a clip of John Carney and The Mums on yet another show, a children's magic show (PBS?), and a ton of other clips.
