Up to now, the only thing that I've really heard from 70s/80s aidoru Miyuki Kosaka（小坂みゆき）was her lovingly techno-quirky "Nuance Shimasho"（ニュアンスしましょう）in 1984, created by the dream team of Taeko Ohnuki（大貫妙子）and EPO.
Then a few months ago, I heard her 21st and final single from November 1989, "Kannazuki ni Kakomarete" (Wrapped Up In The 10th Month of The Lunar Calendar) which is also pretty catchy in a different way. Written and composed by Yosui Inoue（井上陽水）, it's a fairly driving pop/rock tune with the sheen of that decade. I figured that it was probably made as a theme song for some action drama starring Kosaka.
Well, I may be half to completely right on that guess since it was used as the first theme song for an anthology drama series called "Dramatic 22"（ドラマチック22）, so titled because it was broadcast at 10 pm or 2200 hours on TBS. The show lasted for about 18 months and though I didn't go through the entire list of episodes to look for Kosaka, it looks like it starred pretty much all of Japanese show business in one way or another.
The thing is, though, that "Kannazuki ni Kakomarete" was actually originally recorded by Inoue himself for his December 1972 album "Yosui II: Sentimental"（陽水II：センチメンタル）. The album has been classified as a folk release, but Inoue's first take of "Kannazuki ni Kakomarete" also has that same urgency but within a combination of Latin rhythms and light psychedelic rock. It's like doing the tango in a wide-lapeled suit and bell-bottoms while the piano keeps on chugging along.
As for "Yosui II: Sentimental", it peaked at No. 10 on Oricon, and though it took its sweet time, the album became the 8th-ranked release for 1974 and then came in at No. 15 in 1975.
