Along with "Memory Glass", this was another one of my introductions to Kayo Kyoku back in 1981. One of my classmates from Japanese Language school had brought back a ton of VHS tapes with "The Best 10"and "The Top 10", and this tune was played pretty much non-stop. It reached a peak of No. 9 on the Oricon in August.
The title "Machibuse"is translated as "ambush", a pretty aggressive name for an aidoru song, but going over the lyrics, it's much more of a wistful story of unrequited love.
My personal memory of Ishikawa and "Machibuse" was when I was watching my very first viewing of the Kohaku Utagassen when she was the 2nd woman singer to appear after Naoko Kawai. Halfway through the song, she crumpled into a bag of tears since she was so happy to appear on the programme. I guess her emotions "machibuse"ed her.
