For the latest episode, we go back to 1979 and Replicas - a song about terrifying androids with human skin who terrorise humans for fun: 'Down in the Park'. The episode looks at the song's influences, lyrics, history, cover versions, remixes and more. From Machmen to electronic car machines to beautiful piano versions, it's time to look back at one of Gary Numan's best ever songs.
