Britain's favourite soprano, Lesley Garrett, presents an hour of music, inspiration and conversation as Christmas Voices returns for its second series. This week, former prime minister Tony Blair talks exclusively about religion and politics. Lesley's musical guest is soul singer Mica Paris. She will be talking to Lesley and singing live in the studio. The third of our feature choirs from across the UK is Cardiff-based Only Men Aloud singing O Come, O Come Emmanuel and Deck The Halls. And we join a Humanist family to see how they will be celebrating at this time of year.
