Being way too young to enter the discos when Disco was king in the 1970s, my time for cutting up a rug (that expression probably aged me a few more decades) was in the late 1980s when my university buddies and I hit places like the Diamond, the Copa and even the highest disco on the planet at the time, Sparkles, up in the CN Tower. Now that last dance floor was truly a closet pretending to be a disco emporium.
Urban Japan was also not unaware of the disco boom, it seems. I knew about all of those huge dance clubs from the 1990s such as Julianas and Velfarre in Tokyo but wasn't quite sure about how discos were like back in the 1970s. I've heard about those emporiums in Roppongi like the Lexington Queen but perhaps a lot of the dance clubs may have been fairly tiny.
In any case, this is "Disco Lady" by Rie Nakahara（中原理恵）. Released in August 1978, this was her 2nd single following her debut of "Tokyo Lullaby"（東京ららばい）which is the one song that most folks remember her for. The song does have some of that disco beat in there but I'm kinda wondering if it's more in line with some of the uptempo kayo of the time from the two Hiromis...Go and Iwasaki（郷ひろみ・岩崎宏美）. As with "Tokyo Lullaby", Takashi Matsumoto and Kyohei Tsutsumi（松本隆・筒美京平）were responsible for words and music respectively.
