Described by Jonathan Ross as 'a comedy legend' and Matthew Sweet as 'the Truffaut of smut', David McGillivray has enjoyed a colourful career in many areas of lowbrow entertainment. But not even his closest associates, let alone fans of his horror films and comedy plays, could have predicted the extraordinary turn his career took during the final years of the 20th century. What is not so well known is that for several years, 'McG' also supplied class A drugs to a select clientele, which included doctors, lawyers, actors, artists and writers, many of them household names.
