The Bafta-winning reunion show Long Lost Family (ITV) plucks at your heart strings like a concert violinist, and yet it never seems cynical or cheap. That's in large part down to the sensitivity of its two presenters, Davina McCall and Nicky Campbell, both of whom can draw on personal experience of family estrangement.
In this episode, the second of the fourth series, 44-year-old Sarah Price Parker was looking for her birth mother. Her adoptive mother had died when she was only 16 and she said she felt doubly cheated: "I can't imagine what it must be like to have a mum." Pauline Wood, 77, was also adopted at birth, but her biological parents later went on to marry and have another son. It was this brother she hoped to be reunited with, in time for him to give her away at her wedding. Sad stories, but with happy endings.
