'The Smithies' or 'The Smiffies' were a small group of young lads from Deptford, S London. They got their name because the family name of two or three of them was 'Smith' (brothers, or cousins), and that name stuck to the whole bunch. They got pocket money by collecting and selling scrap (yes, they were proper 'totters'). I met the bloke on the extreme left of the photo a couple of times. I remember he came to my college in New Cross for an open-air concert.
