I clearly remember this series and it was almost compulsory viewing in our house. Such programs tended to have a high interest value and impact on boys of our age at that time. Looking for evidence of the series I couldn't understand why there was no trace of it on YouTube until I found the following note on Wikipedia: "The BBC (1965).....16-episode TV series ........Hereward the Wake, based on Kingsley's novel. Hereward was portrayed by actor Alfred Lynch. NOT ONE EPISODE of this BBC series has survived, according to the archive records." Very sad indeed as the series could now almost be considered a historical record in its right.
