"All Around My Hat (song)" — The song is of nineteenth-century English origin but nevertheless features very prominently in the plot of the episode "The Prisoner". It is claimed to be a favourite song of the crusading King Richard and is constantly sung by the king's courier who has been secretly imprisoned in Prince John's dungeon. The tune is so charismatic that a dungeon jailer sings it while drinking at a tavern and is overhead by Robin Hood, thus alerting Robin of the courier's fate.
