Hey youngsters! Gangnam style no more. Here comes Gelan style. Gelan?? This is the Hanyu Pinyin (Chinese) name for Grace Chang. Grace Chang?? Aiyoh!! Below is the "copy & paste" from Wikipedia.
She was an actress from the Cathay (Motion Picture and General Investments Limited) with many successes from "It Blossoms Again" to "The Wild, Wild Rose" and "Mambo Girl".
Chang appeared in 33 films during her 11-year acting career. Her last actual appearance was in 1964 though she has provided vocals for soundtracks.
Now before you click off the video, the action begins @ 1:50 of the Youtube track. Mind you Gelan is still alive in Hong Kong, perhaps waiting for Psy to do the mambo with her.
