This is a song by Kaguyahime released in January 1974!
According to Wikipedia, it's the second song in the "Four-and-a-Half Tatami Mat Trilogy," following "Kandagawa," and apparently "Imouto yo" (My Little Sister) followed it.
At the time, the audience consisted of folk music lovers, so I decided to perform this song without any prior announcement.
As expected, it was a well-known classic! (^^♪
