In 2018, a newly restored print was broadcast, after the original film - sent out as an audition print - was found in an abandoned cinema in Freetown, Sierra Leone. It was then visually cleaned up and restored to remove film dirt etc, then digitally reverse-engineered to appear like 25/50 frames per second video, as well as adding in the available colour data using the chromadot process. This is why it has an even stranger appearance, even for a 1960s colour video.
The original version of this episode contains a comedy sketch featuring the "original" IRA ("Irish Republican Army") seemingly set some time in the 1910s-1930s. This sketch was broadcast just before the 1960s "Troubles" in Northern Ireland "began", which also involved a later version of the IRA. Perhaps surprisingly, the 2018 restoration version left this sequence in, and possibly completely uncut from the original version. As of 2020, the scene is still in the version broadcast on BBC 4.
