Radio Wales reporter Chris Dearden showed he was paying attention when the children's television series Ivor the Engine was screened while he was a boy.
Chris was reporting from Snowdon Mountain Railway where episodes of the much-loved series created by Oliver Postgate are being shown before visitors can board a real steam train.
He had just finished interviewing Stephen Postgate, Oliver's son, when he was quizzed from the Radio Wales studio in Cardiff by Oliver Hides and Sarah Dickins about his knowledge of programme.
