ARTS & SOCIETY FORUM: When Patrick Marmion first saw Stephen Berkoff’s Greek as a student back in the Eighties at the Edinburgh Festival it blew his head off. A notoriously difficult man himself who has been accused of all sorts of sexual transgression, there are aspects of his writing which are gloriously uncomfortable for today’s audiences. And yet with all the repressive puritanism that’s accompanied the counter revolution against the liberalism of the Sixties and Seventies, too many writers have lost touch with their creative libidos and we have grown accustomed to a theatre that is led by bloodless, neutered moralists. Patrick Marmion and Wendy Earle discuss.
