Following the death of the Duke of Edinburgh, William Crawley looks back on his life and reflects on his faith with Bishop Graham James, Chief Rabbi Ephraim Mirvis, historian Coryne Hall and the writer Martin Palmer.

Also in the programme, as violence returns to the streets of Northern Ireland, how significant is this moment and do religious leaders have any influence on events? With the Catholic Bishop Noel Treanor, and the Presbyterian Moderator, Dr David Bruce.

And the musicologist Michael Spitzer, author of the new book 'The Musical Human: A History of Life on Earth', explores how music was fundamental to our evolution and its relationship to religious and spiritual beliefs across the world and across time.
