Is this the one? These old videos were what got me interested in the Singer/Mendelson duo 10 years ago. It reminded me of when Uri Geller bamboozled the Stanford Research Institute using some impromptu and fairly obvious "magic tricks." The SRI and Geller wound up tied together forever.
Ten years ago, my first impression of the interview had to do with, "Why the hell is Rob wearing that shirt for a serious interview?" The rule of thumb for lectures or interviews is that if what you have to say is worthwhile and you know what you're talking about, you don't wear a distraction. Alan maybe should have coached him into different sartorial choices, but it's also possible Alan didn't want to be doing any kinds of coaching for an interview.
Looking at the videos now, I have no idea why Rob makes an occasional crack about my weight (I'm maybe 15 pounds overweight). Rob looks way worse in other sessions than I do weight-wise.
As for Rob's hair, as I say about myself, "It is what it ain't." After the first three months of pandemic, I finally took off my baseball cap, and my hair had that similar Larry Fine look to it. I immediately had my girlfriend shave it all off.
