Rising to fame amid the 1980s alternative comedy boom, Ian Cognito was one of the UK's most popular comedians. His performances left audiences in hysterics - but behind the laughter was a troubled and often controversial figure. This is the story of the comedy scene that nurtured a comedic genius, and the real life of a man famed for his outlandish sense of humour.

In the late Eighties, there had been a series of comedy concerts (modelled on the Amnesty International “Secret Policeman’s Ball series”) to raise both awareness and raw cash for HIV/AIDS charities. The series was called Hysteria to reflect the hysteria (and downright untruths) surrounding the issue of HIV/AIDS. The last one of these had been in 1989, so in 1994, Pozzitive set out to revive the idea of a fundraiser with “Filth!” a night of comedy and music at the Sadlers Wells theatre, on Sunday 24 April. In fact, so many comedians and writers said “yes” to the idea, that we hit on the notion of doing two shows in one evening back to back. The first show was hosted by Lynn Ferguson and Arthur Smith, the second show by Mark Lamarr. Artists involved in the show included Tom Robinson, Steve Coogan, Spitting Image, Eddie Izzard, Jo Brand, Jeremy Hardy and Ben Elton.
