MANY are the requests that come our way. But Sarah Smith appears to have given us a real challenge. Sarah, a member of the Not So Loud Theatre Company, wants our help to pack the Fringe to the rafters from today until Saturday for a play entitled Chicken Wings, which draws its inspiration from the Vietnamese boat people. ''All of us in the cast are professionals - lawyers, marketing consultants, advertising executives and so on. But our pleasure and reward will come from the audience - we need one every day this week,'' implores Sarah, who does marketing for a holiday resorts company. The drama - which had a sellout run at the Fringe Festival this year - is being re-run to raise funds for Amnesty International, which has been active in helping inmates at the Vietnamese camps to obtain refugee status. In fact, the play's title is derived from camp terminology; anyone refused refugee status is referred to as ''getting their chicken wings'' (ie unable to fly out). Sarah adds: ''At our theatre company we like to perform new plays. So if there is anyone out there who has written a play and is looking for someone to put it on, we will be happy to oblige''. So there's hope yet for all you budding playwrights. Just contact Sarah (977 8777) or the company's director, Tom Hope (842 4843).
