Ahhhh....the 1980s...when aidoru songs can sound like tunes from the 1920s. Well, at least, this particular one. For the longest time, I thought "Hatto Shite! Good" had been sung by Masahiko Kondo（近藤真彦）but it was actually the other member of the Tanokin Trio collective, Toshihiko Tahara (田原俊彦...to be honest, I often couldn't tell the two apart, and I usually forgot who that third member was, Yoshio Nomura/野村義男).
Released in September 1980, this was Toshi-chan's 2nd single. I was kinda wondering what the first part of the title meant but after going through the lyrics about a young fellow suddenly running into the girl of his dreams, I realized that the "Hatto Shite" was somewhat onomatopoeic with Tahara going "BOING!" on seeing her. I thought it was cute and clever how that turn of phrase went in the lyrics: "Hatto shite, gutto kite, patto mezameru, koi dakara"（ハッとして、グッときて、パッと目覚める、恋だから...I go BOING, then I go GULP, and my eyes go SNAP, cause it's love）. That phrase could pretty much describe that moment that every boy that had ever lived on the planet Earth experienced when l'amour struck for the first time.
