Bach-Tuyet & Hoai Vinh Phuc / Ngoc-Giau - Nhac ru'ng dem / San khau ve khuya 7" (Continental, C.167-566)
Here is some more lounge-traditional-lounge -formula on A-side with female & male alternating vocal duties. B-side being musically more minimal with female singing, talking and something in-between. As I mentioned before, Vietnamese singles seem to be quite long in duration but this one makes a record so far, lasting 16½ minutes!
I noticed that there exists also another 7" with the same catalogue number on same label (which I'll digitize later). That makes documenting Viet vinyls even more confusing, good luck to anyone who makes an effort.
