What would the children of today make of our childhoods? Four 21st-century guinea pigs are given the opportunity to sample BBC children's television from the past five decades. They will also try out the clothes, games and food from each era. In return they will offer candid observations on the programmes from our treasured past. Will the kids be kind? With contributions from Brett Adams, Johhny Ball, Floella Benjamin, John Craven, Bernard Cribbins, Terry Nutkins, Sylvia Peters, Peter Purves and Peter Simon.
