To open people up a bit before you even start, the tip from Derren Brown's 'Absolute Magic' works - if it's not that book please correct me - he says he introduces himself thus:
"Hi my names Derren and I'm a
kind of magician..."
I've used it a few times on people that know me but don't know I enjoy magic and they become so intrigued. It would definitely help you out in a close-up mentalism situation.
It's a great opener for Henry Sugar:
"...and I'm a
kind of magician - I'll show you what I mean. Do you know the story of Henry Sugar? You don't? Well..."
Anyway, hope that helps.
