Once again, our very own Lady of Mystery has hit the nail on the head!
As I've said before, I love Osterlinds routine in 'Very Modern Mind Reader'. Is it the same as DB's Oracle Act? No - because it involves you moving out amongst the specs to hand out the cards and envelopes and then have them sealed and handed back to you. But it's perfect for most of us, it's got misdirection in movement and a foolproof way of gaining the info.
Now, this method won't work for Derren because he's playing to 1,000+ seater auditoriums. But most of us aren't!! I can see why Eshly might be interested to know DBs method out of curiosity but I (as I'm sure all of us!) can think of a number of ways that he can get the info.
Lady of Mystery talks of Corinda - in fact if you look at the recently released DVDs (Osterlind again!), I'm positive that they reveal the
exact method used by Derren to gain at least some of the info during 'Evening Of Wonders'
However, this thread has peaked my interest in Q&A again and I think I may have to bring it back into my act sometime soon
