A thousand programmes later ... ' Way back in 1966, if anyone had told me that during the next 12 years I'd make a five-mile fall out of an aeroplane, crash at 90 mph on a bob-sleigh, climb to the top of Nelson's Column-twice, become a cook, vault over a ditch and be trodden on by an elephant, I'd never have believed them! But they've all happened to me during my thousand or so appearances on Blue Peter. Today you can watch some of those extraordinary experiences.' (JOHN NOAKES )
