Thanks to Nick Prince for the footage.
Mayfair aka St Ethelbert's Fair has been held in Hereford city centre since 1121.The fair has been taking place on an annual basis since 1121 when King Henry 1 granted Bishop Richard rights to hold a nine day fair in Hereford city. This was reduced to three days in 1838 by an Act of Parliament.
This footage is late 1960's or very early 1970's.
