Tony, from Essex, has been demonstrating his psychic powers for 19 years.

"A dedicated worker for spirit, Tony has worked hard to fine tune his craft, building a reputation of excellence in public demonstrations", says his promoter.

Tony runs workshops and seminars and is a regular at the Arthur Findlay College of Psychic Studies at Stanstead Hall, run by the Spiritualist National Union (SNU).

Tony has appeared on TV in the series Street Psychic, Psychic Detective and Psychic School.

In 1999, Tony and Stuart Borley set up the Avalon Project to promote and encourage spiritual learning, development and understanding.

Tony says he wanted to offer the kind of workshops, lectures and other events that he would have wanted to attend as a developing medium.

He has written three books, Spirited, Embracing Eternity and the latest, The Psychic Detective, and produced CDs for meditation and development.

Janet Parker has been a medium and psychic teacher for many years. She learnt from the late Gordon Higginson, who she says was known in spiritualist circles as one of the world's best physical mediums.

Janet, who has been president of the SNU for 20 years, travels extensively in Europe, the USA and Canada, giving demonstrations, lectures and workshops. She is a tutor at the Arthur Findlay College.

She recently gave a seminar and workshop to a support group for people who had lost children, in Italy. She says the audience included Catholic priests and Franciscan monks who gave her a warm reception and showed great understanding.

She says: "There should be no condemnation without investigation or examination. There are some who will never be convinced. My job is to make people think".

The event is being promoted by a small shop in the Market Vaults which sells books of a spiritual nature, cards, crystals and gemstone jewellery.

The show is on Thursday May 1, at 7pm.
