Almost 50 years ago, John Guerin lost touch with a friend. They had met while training to be engineers in England.

John is currently in Ennis hospital being treated for an aggressive form of Motor Neuron Disease. His health and speech have deteriorated. But he managed to tell his sister, Margaret, that he dearly wants to find his old friend.

Nearly 50 years since the two Johns saw each other, it's become a mission for the Guerin family to find 'Big John' Moran. Margaret Guerin came on Liveline to ask listeners for their help.

After the callout, John Moran from Termonfeckin rang into the show. Listen to the incredible moment he and Margaret spoke on air above.
