Lee Wei
During the 1980s and 1990s, Moo was part of the "xinyao" movement and his peers included Lee Wei Song, Lee Shih Shiong, Billy Koh and Liang Wern Fook. One of his more memorable songs is "Kopi O" (咖啡乌), which he performed himself for the popular SBC 1985 drama series "The Coffee Shop". At the Star Awards 2007 anniversary special, he revealed that he had insisted on using the term "Kopi O" in its original Hokkien rather than transliterating it into Mandarin according to the Speak Mandarin Campaign regulations.
