Natalie Maddix, founder of the House Gospel Choir, explains why she believes in the power of singing together. She gets the audience at WOMAD to join in to prove her point.

"Singing really has this healing property. There is a truth inside of us that maybe we're not ready to face and sometimes it's not until we sing together that we even become aware of our feelings."

Recorded in front of a live audience at the WOMAD world music and arts festival in Wiltshire.
