Bristol Underground Church

I've had a nice letter from this organisation, depicting ten smiling young people, about their work in Nailsea recently and asking for some fliers from our church. I intend to try and meet them for a chat.

Googling only produces one hit, and that this description of being evangelised on the streets of Stoke Croft by someone not interested. Anyone know any more?

The letter writers call themselves Apostle Simon and prophetess Bridget.
