No. That old chestnut was done this way.
Before the show, guests would be asked to write a question on a piece of paper to be chosen at random by the "mind reader" during the show.
He would start by pulling a question out and giving an answer that could fit just about anyone in the audience. He might say something like, "Everything will work out fine with your children - it's just a phase." If no one in the audience has written a question that would cover this answer, the mind reader's "plant" will jump feigning surprise asking how he could possible have known that question without reading it.
The mind reader then opens the paper and reads it acknowledging that this was indeed the question. What he is really doing is reading an unknown question in advance. Now he will take another paper holding it to his forehead, etc. and proceeds to deal with the question he has just read. After that question, he "confirms" the question by reading it aloud (quoting the previous question) and gets to read the next question in advance.
It was very impressive in its time.
