Today's show was dedicated to everyone whose day to day routine involves a locker! And the show was entitled "If you try it you'll know, if you don't you won't." Joseph Wayley aged six from Grantham is going to his first school council meeting today, and will come back tomorrow to mark it out of ten. The Doyenne of British Cookery and all-round National Treasure, Marguerite Patten CBE was today's Mystery Guest.
