I've been forgetting to recommend the documentary series on SBS that was started last Monday - Derren Brown Investigates. I am unfamiliar with Brown, but he appears to be a well known illusionist in England who specialises in faking psychic abilities.
This first episode was devoted to his following around a medium in Liverpool - Joe Power - a middle aged man who seems to have a reasonable business at the local level in giving private readings and the occasional group show in smallish venues.
It was all pretty fascinating, as Derren dealt with the issue of whether Power was a fake or not in a polite but insistent way. The show contained a great summary in the middle of the various techniques used in "cold readings".
As the flakiness of Power became clearer and clearer through the show, I almost started to feel sorry for him for not being bright enough to not put himself at risk of exposure. You have to watch to the very last to find out the explanation as to how Power did his apparently successful reading at the start of the show. (OK, there is no 100% proof against him; just an obvious way that he could have obtained the information.)
You can still see it on SBS on Demand for another week or so, if this is of interest, but the whole thing is also on Youtube.
The show also reminded of John Edward, who has obviously made a squillion from his mediumship shows, and how he is obviously open to the charge that he uses "cold reading" techniques, yet similarly seems to occasionally pull surprisingly relevant detail out of the air.
Given that he is such a "rich" target, and that his show obviously has so many people involved in its production, it is a wonder that there has never been anyone associated with it who has (to my knowledge) come out with explanations of how he has sometimes had convincing sounding "hits" on his TV or stage shows.
I remember reading somewhere that his Australian tours produced some pretty unconvincing shows. I think he even claimed the problem was he often couldn't fully understand spirits with Australian accents!
But as far as mediums go, I do find him a bit unusually likeable in demeanour. Joe Power seemed a bit of a sad, arrogant type who lived alone.
