St John Ambulance
Centenary Celebrations
Sarah Kennedy and Phillip Schofield introduce the highlights of today's events in Hyde Park, London, where HM The Queen opened the world's largest children's party.
Eric Robson describes the day's events, which include a live link-up with the St John Ophthalmic Hospital in Jerusalem, as well as all the carnival fun in the park with such bizarre items as the world's longest sausage - over seven miles long! The day ends with the children joining the volunteers of St John Ambulance and celebrities who support the Brigade for a grand finale sing-along.
