The first of five films in which a group of Welshmen recall their part in the Spanish Civil War. How the Red Road Began.
Most of those who went to Spain from Wales were unemployed miners who had fought the injustices of the 1930s in strikes, riots, demonstrations and hunger marches. Many were Communist. Why did they go to Spain? Gwyn Thomas , 12th child of a Rhondda miner, first saw the country as a student in 1933. Narrated by RENÃ‰ CUTFORTH Film editor BILL MAINMAN
Written and produced by JOHN ORMOND

A Ripe Old Age
The six famous people in this series are news for a special reason. They're all past the normal retiring age, but they're working as hard as ever. One describes himself as a workaholic, and, says Fyfe Robertson , you could use this handy word for them all.
In the volume and speed of her output as a romantic novelist Barbara Cartland is surely the most astonishing work addict of the six. In one year she has dictated novels faster than many can read them - about one a fortnight. At 78, she talks as fluently and unstoppably as she writes.

Ten films in which Magnus Magnusson explores the Viking world. 9: Empire of the Northern Seas
The Atlantic isles of Shetland and Orkney were a Viking world in miniature.
Tonight MAGNUS MAGNUSSON looks for the relics of his namesake St Magnus in the walls of Kirkwall Cathedral and for the spirit of Earl Thorfinn the Mighty, who presided over a golden age of Viking life from his impregnable palace stronghold.
In the south the story is still one of blood and invasion - and a legacy of bizarre Viking legend: a children's song which celebrates a Viking command raid, 'Dane-skins' nailed to the doors of country churches and a great and wise Viking king who could not command the rising tide. with Jeremy Kemp , John Bennett
