I found this piece about magician, Mike Stoner, who works in the Berkshire area, and has performed for Jimmy (presumably at one of his (JP's) parties).
Specialising in: Close-up Magic
Ideal for: Weddings, Parties, Dinners, Trade Shows & Exhibitions
Based in: Berkshire (entertains nationwide)
Mike Stoner is a full-time professional magician and mind-reader who entertains with a mixture of traditional magic, modern fast-moving psychological magic, palm-reading and metal bending. Mix one third Paul Zenon, one third Uri Geller and one third Derren Brown and you'll be about right. He does magic at parties, weddings, restaurants and corporate events across Southern England several times every week and has performed for celebrities such as legendary Led Zeppelin guitarist Jimmy Page and Home Secretary Theresa May.
