In the hot, dry summer of 1976, Mary Joy Langdon made a very bold decision: she joined the fire service. She was the first woman in the UK to work as a professional operational fire-fighter. Then, after eight years, she changed course - and became a nun.

In 1989, as Sister Mary Joy Langdon, she founded the Wormwood Scrubs Pony Centre, introducing inner-city children and young people with disabilities to horse riding. Recently it helped children traumatised by the Grenfell Tower fire. The Centre also attracted one of Britain’s most acclaimed painters – Lucian Freud - who came to draw the horses.

Mary Joy's music selections include Mozart, Strauss, Bach and Grieg.
