to 1969). He launched a British version (1967 to 1973), which was A4 (as opposed to IT's broadsheet format). Very quickly, the relaunched Oz shed its more austere satire magazine image and became a mouthpiece of the underground. It was the most colourful and visually adventurous of the alternative press (sometimes to the point of near-illegibility), with designers like Martin Sharp. Other publications followed, such as Friends (later Frendz), based in the Ladbroke Grove area of London; Ink, which was more overtly political; and Gandalf's Garden which espoused the mystic path. Legal challenges The flaunting of sexuality within the underground press provoked prosecution. IT was taken to court for publishing small ads for homosexuals; despite the 1967 legalisation of homosexuality between consenting adults in private, importuning remained subject to prosecution. Publication of the Oz "School Kids" issue brought charges against the three Oz editors, who were convicted and given jail sentences. This was the first time the Obscene Publications Act 1959 was combined with a moral conspiracy charge. The convictions were, however, overturned on appeal. Harassment and intimidation Police harassment of the British underground, in general, became commonplace, to the point that in 1967 the police seemed to focus in particular on the apparent source of agitation: the underground press.

If anything, according to one or two who were there at the time, it actually made the underground press stronger. "It focused attention, stiffened resolve, and tended to confirm that what we were doing was considered dangerous to the establishment", remembered Mick Farren. From April 1967, and for some while later, the police raided the offices of International Times to try, it was alleged, to force the paper out of business. In order to raise money for IT a benefit event was put together, "The 14 Hour Technicolor Dream" Alexandra Palace on 29 April 1967. On one occasion – in the wake of yet another raid on IT – London's alternative press succeeded in pulling off what was billed as a 'reprisal attack' on the police. The paper Black Dwarf published a detailed floor-by-floor 'Guide to Scotland Yard', complete with diagrams, descriptions of locks on particular doors, and snippets of overheard conversation. The anonymous author, or 'blue dwarf', as he styled himself, claimed to have perused archive files, and even to have sampled one or
