Caught a rerun of an NHK kayo program yesterday afternoon, and one of the featured guests was the group Hayabusa（はやぶさ）with their return of the good ol' kayo in the 21st century. I first mentioned about them in late 2017, and since then, the trio has been whittled down to a duo (just Hikaru and Yamato now).
Hayabusa performed their September 2019 single "Choten Fever!" (Ultra Heaven Fever!), an odd amalgam of enka and disco as the main vocalist Hikaru sings about the good life in the dance clubs with that characteristic vibrato of the former genre done to the beat of the latter genre. As Hikaru goes high, Yamato goes low like the bass guy of a doo-wop group. Written and composed by Kenichi Maeyamada（前山田健一）, who I usually associate with zany anison, "Choten Fever!" sounds as if it should have been a theme for an anime somewhere, and sure enough, it was one of the opening themes for "Duel Masters!!" in 2017. It doesn't quite hit the mark for me, but it's fun and quirky enough that I had to mention it.
