At one stage of the show there was a video image shown on the 'wall' of children who were visited by their fathers who had returned from war and had gone into the classroom to surprise them. The camera captured the faces as they each saw their dads walk in. There was one image I will never forget. The camera went to a girl's face who was sitting at the back of the class. She looked about eight. She looked up, initially shocked at seeing her dad, then a gradual wave of realisation crept over her face that her father had just walked in. She smiled broadly, almost laughing, eyes sparkling, and then her face crumbled, slowly collapsing into overwhelming uncontrollable emotion that there was her daddy, her daddy and she hadn't seen him for so, for far too long. He had to physically pick her up as she literally collapsed, hugging him so tight, tears blistering down her little face.
Walking back the conversations in the car park were not I imagine the same that you would hear having heard Take That or West Life. Could be wrong.
