There'd be a microphone set up in the Tower of London.

Connected live?

Yeah.

My grandfather then comes on the air and sets up a series of telepathy tests that they're going to enact.

So there was a famous one called the book test and this is where a member of the audience would come up to the stage and there'd be a pile of books and they'd randomly pick up a book, randomly open to a page and point to a line.

Now... Completely random bit of text selected out of a stack of books.

After the text had been chosen and only then... I shall now call in the Tower of London.

They would connect to his grandma, Leslie.

And a gong would sound and...

He'd kind of very dramatically furrow his brow.

And the next thing you heard was... Men.

My grandmother.

Men.

This sort of frail, gentle voice.

And she started to unpick what was being transmitted to her.

Remember that line again was?

It's amazing to listen to.

Over 60 years later, listening to those tapes, I'm still on the edge of my seat.

And right at the end.

Almost every time it would be 100% correct.
