I saw that 46th annual "Omoide no Melody"（思い出のメロディー）special, as I mentioned for another article, and one other song being performed was by 70s heartthrob, Hideki Saijo（西城秀樹）. As soon as I heard the call-and-back of "HIDEKI!" from the audience, I recognized the song but hadn't known the title. It turned out to be "Jounetsu no Arashi" (Passion Storm) by lyricist Takashi Taka（たかたかし） and composer Kunihiko Suzuki（鈴木邦彦）. For the above video, it is the song following his famous version of "Y.M.C.A."
Released in May 1973, "Jounetsu no Arashi" hinted at some smoldering love from Saijo which I'm sure the audience's screaming of the lad's name was further fueled by. Having seen one of his old concerts on VHS tape way back when, the tall handsome lad knew how to whip up a crowd into a frenzy. He wasn't quite as energetic on the NHK stage a few nights ago, but the audience was still willing to yell his name.
