I actually heard this on YouTube's J-Channel last week and I was rather glad that I could find it elsewhere on the site.
Not knowing too much of Machiko Watanabe's（渡辺真知子）material after the 1970s, it's great to know that she's been behind songs such as "Hoshi Furu Yoru ni Ki wo Tsukete" (Be Careful on the Night When The Stars Fall) which was a track on her 1987 album "Soi". Written by Watanabe and composed by Minoru Komorita（小森田実）, the song is an appealing mix of that late 1980s sophisticated City Pop, sultry Latin and perhaps even a hint of Matt Bianco. It's pretty darn classy; I can only see this in the setting of some of the more expensive parts of Tokyo, and Watanabe's voice gracefully adorns any imagined couple tripping the light fantastic on the tango floor.
Well, thanks to uploader and commenter Midori, here is the full recorded version! My gratitude!
