This Songs of Praise special asks what the death of Diana, Princess of Wales, has taught us about the value of life and the cost of love.
Diane-Louise Jordan talks to a couple whose nine-year-old daughter was killed in a road accident about coming to terms with grief and loss, and looks at the continuing work of Diana's favourite charities and efforts to create a fitting memorial for the Princess.
As well as music from Sarah Brightman, Adrian Snell, and the Chicken Shed Choir, hymns sung by the BBC Singers and Caernafon Male Voice Choir include the Princess's favourites Make Me a Channel of Your Peace, I Vow to Thee My Country, and Breathe on Me Breath of God, and a Welsh version of the Lord's Prayer.
(The Art of Diana is at 10pm.)
