Sir - As a playgoer of forty years standing, may I say that I heartily agree with Peter Pinnell in his condemnation of Entertaining Mr Sloane.I myself was nauseated by this endless parade of mental and physical perversion. And to be told that such a disgusting piece of filth now passes for humour!Today's young playwrights take it upon themselves to flaunt their contempt for ordinary decent people. I hope that the ordinary decent people of this country will shortly strike back!Yours truly,Edna Welthorpe (Mrs)
