Since that time he has developed an addiction to sceptical literature as well as a fascination with magic, cognitive psychology and nice cheeses. In 2008 Jon travelled to Basrah, Iraq, to record an album with some military pipers. He also offered ‘psychic surgeon’ Gary Mannion £50,000 if he could demonstrate his claimed abilities under test conditions. Jon’s cat Foxy is able to recount pi to one hundred and fifty decimal places.

Starting out at just a few visitors a day, the BP network now regularly averages over 5 million page views per month, making it possibly the most popular sceptical community in the UK.
