Had coffee with my brother from about 10pm till alround 11:20pm at the foodcourt nearby, and saw Liang Wenfu having coffee there.
Liang Wenfu is a XinYao singer, back in the 80s and probably 90s. It would appear that he's still a lecturer in the NUS, though I can't tell for sure.
I have some of his songs on MP3, and one of the songs I love is his “Xi Shui Chang Liu” (roughly: smooth water runs long or 细 水长流) and “Li Shi Kao Shi Qian Xi” (The Night before the History exam).
