Mike Murphy, famous for catching out celebrities on candid camera, gets caught out by Professor F.X. Martin live on 'The Mike Murphy Show' on RTÉ Radio. F.X. Martin is a guest on the show to discuss Viking Dublin and suggests to Mike Murphy that Christ Church Cathedral will be demolished. He describes parts of the north wall of the cathedral as unsafe and says it is likely that the cathedral will be demolished. As Chairman of the Friends of Medieval Dublin and a Priest, F.X. Martin is a trusted source when it comes to information on historic Dublin.
