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
