Peter Lai is only good at writing songs but not singing them. Wai Fun is "host," but habituated to refer lyrics , in spite of singing for donkey years ,and refused to memorise them , unlike Auntie Tham Sin Hung. This has earned her a nake name ," Cat 's paper Queen" , even those days singing with late Chung Wan San. She also refused to spill out words fr mouth ,almost keeping mouth tight , like biting teeth , when singing. Sorry for the offence. TQ
