On that subject, I get a different answer on this depending on where you were living and how old you were, but:
when do you remember the crop as being the cool haircut to have?
Did you ever have a crop? If not, what?
When did you grow it? what was the turning point?
What did you ask for at the barbers?
in 1968/69 my regular barber was in Brockley, London SE4. I used to ask him for a 'skinhead cut'. He would say "You mean shorter than skinhead", and proceed to give me the kind of short college-boy cut you can see in my photos. I never had a No.1 (until recently - the alternative is a Gregor Fisher 'Baldy Man'!). What this tells me is that back then 'skinhead' did start as a nickname for us 'late mod'/'totter'/whatever types.
