Well, from such humble beginnings...if memory serves me correctly, the above two cool actors are Takeshi Kaga（鹿賀丈史）and Yosuke Eguchi（江口洋介）. Namely, it's the Chairman from "Iron Chefs" and the feckless Mikami from "Tokyo Love Story" respectively. Apparently, they were in the NTV detective series "Jungle" as two intrepid gumshoes in its second season in 1988.
Both Kaga and Eguchi can sing, but this article is not about either of them this time. Actually the single version of the opening theme, "Dangerous Night" by saxophonist Jake H. Concepcion was released with the B-side being the actual song du article, "Long Way To Love" by singer-songwriter Masayuki Kishi（岸正之）.
Quite a soothing urban contemporary ballad by Kishi, there is something very Omega Tribe and Tetsuji Hayashi（林哲司）about "Long Way To Love". Now that the summer seems to be finally making its way here, I would be more than happy to listen to this again while lying on a lanai and sipping a cocktail as the sun goes below the horizon. That sax solo also sounds very Carpenteresque.
There is no mention of this song at all even on his own website so it was pure luck that I came across this little gem.
