Jane, who used to practise psychotherapy and reiki in London, met Tony at a dance camp in 1989. "I had wanted to have an alternative life," she says.

"There comes a time in this sort of life where you think 'this is life', you are not trying any more to do all these busy things to avoid chores – they are part of it all."
