The British Pathe organisation that made many of the newsreels of the twentieth century has digitised them and they are online. They include a couple of Hemyock in the early 1920s
It is of course for the Calf Club that the cameras were brought down for. Here is a link to the website: www.britishpathe.com Should be some old rellies there!
Just look at those hairstyles.
There also some quite interesting videos if you go to Youtube and search for Hemyock.
