I have a vague memory of Christopher Trace being interviewed on BBC quite a few years after he'd left Blue Peter, where he mentioned that the technicians at "It's a Square World" played a dastardly trick on him. Older folk like me might recall their clever and funny special effects. Anyway, the story was that, unbeknown to him, those technicians built a replica of the Blue Peter layout - then blew it to bits! Enter CT later to find 'his' layout totally destroyed, then being shown his actual creation safe and sound in another room! Anyone here on RMWeb to verify that story / my memory?
