From conkers to marbles, from skipping to tag, not forgetting 'one potato, two potato' and 'eeny, meeny, miny, mo', "Lore of the Playground "explores the world of Britain's playgrounds, and looks at the games children have enjoyed and the rhymes they have chanted over the past hundred years and more. Each generation, it emerges, has had its own favourites - Knock Down Ginger in the 1950s, Chain Tig in the 1970s. Some pastimes, such as skipping, have proved remarkably resilient, their complicated rules carefully handed down from one class to the next. Many are now the stuff of distant memory. And some traditions have proved to be strongly regional, loved by children in one part of the country, unknown to those elsewhere. All are brilliantly and meticulously recorded by Steve Roud, who has drawn on interviews with hundreds of people aged from 8 to 80, to create a fascinating picture of all our childhoods.
