Having been incarcerated in the Towers for a year between leaving public school in 1968 and starting at London University in 1969, I can assure you that the culture shock of the pulchritude of those hippy-chic girls was absolutely delightful!
There were some Alvin Stardust look-alike blokes with silly sideburns and long hair around back then, but most looked pretty scruffy. As did those ridiculous 'Viva Zapata' Mexican moustaches affected by some.
