HERE'S art imitating life - with Governor Chris Patten being shifted from the political to the theatrical stage. He is the main element in a play being performed by the Zuni Icosahedron theatre group, the title of which is quite a mouthful. So if you have a few moments to spare here we go: 2 or 3 Scenes . . . Hongkong - No revolution like show revolution. Directed by Danny Yung, the cast includes an interesting name, Legislative Councillor Yeung Sum, who is deputy chairman of the United Democrats. And with Yeung treading the boards (Sha Tin Town Hall, May 8 and 9) we can be sure the play's theme of ''smooth transition towards stability and prosperity for Hongkong'' will certainly not be presented from a pro-China perspective. While on the subject of Mr Patten, how about this Confucian (or confusing!) joke doing the rounds in the cloistered compounds (we have informants everywhere, folks) of the Beijing cadres. A fairy appears in the presence of Lu Ping, China's top Hongkong affairs man, and offers to grant him anything he wishes. ''Arrange to have Chris Patten sent back to Britain,'' he requests. ''Why - would that make you happy?'' the fairy asks. ''No,'' replies Lu, ''but it would certainly make Patten miserable.''
