We hear about a rare meeting between a living organ donor and the child whose life was transformed by receiving her kidney. Aly Coyle says she was delighted to see 5-year-old Xavier happy and healthy after the transplant. His parents tracked her down through social media to say thank you, and describe her as an angel who's now part of their family. Also: how a new machine could dramatically increase the number of liver transplants, by improving the way the organs are stored outside the body. A media company run for and by young disabled people that's hoping to challenge stereotypes and promote discussion. A grand prix with a difference - why cows, and their riders, race through a small Swiss village. Plus: the newly rediscovered works of Bach that have been performed for the first time in over three hundred years. And why more men are taking up knitting.
