Oldrocker was the first person to be Photographed in the UK not wearing a hat*. This caused a sensation at the time and caused hat sales to plummet the following year to one less than the year before. A position that the industry has never recovered from.
*This does not include poor people of course, most of whom had never even seen a hat, let alone owned one. And even if they had they would only have tried to eat it probably...Anyway next week '1963, Don Rushmore and the invention of the polo neck'.
