Found this one not in the "Light Mellow ~ Twilight" as you can see above but in the "Breeze" CD.
Naoya Matsuoka（松岡直也）has been known as a Latin jazz/fusion specialist and also as the composer behind Akina Nakamori's（中森明菜）big hit "Meu amor e" in the mid-1980s. Through "Breeze" though, I found out that the first single (his debut album was "Joyful Feet" in 1977) of his to come out was a collaboration between him and singer-songwriter and R&B chanteuse Minako Yoshida（吉田美奈子）in 1979 called "Lovin' Mighty Fire" as a 12" single.
With Matsuoka behind the music and arrangement, Yoshida handled the lyrics under her pen name of Minnie Shady. The result is a 7-minute-and-change disco groove interlude that had me thinking Chaka Khan. Minaka Khan? In any case, the first time that I heard this, I just had to make sure within the liner notes of "Breeze" that it was indeed only Matsuoka and Yoshida involved without any help from the Chicago-born R&B legend. Indeed, the jazz/fusion specialist and Minnie Shady took care of this, and it's a corker of a tune. The additional funkiness was provided by Matsuoka's band, Wishing.
