Yamaguchi's song, released in July 1977, was her 18th single and the 3rd of 12 singles that the husband-&-wife team of Ryudo Uzaki and Yoko Aki（宇崎竜童・阿木耀子）would pen during the last half of her career. It peaked at No. 2 on the Oricon charts and most likely would've made it to the top but Kenji Sawada's（沢田研二） "Katte ni Shiyagare"and Pink Lady's "Nagisa no Sinbad"(both already profiled) were just too powerful. It would become the 20th-ranked song of the year, and the song was also a track on her 12th album, "Golden Flight", released in August 1977. It managed to reach No. 3 on the album charts.
But even though she was 18 at the time, she certainly didn't look nor sound like a callow high school senior when she performed "Imitation Gold". Her lower voice gave an effectively blase account of a seen-it-all, done-it-all lady who went through men like most people went through a box of chocolates over the Holidays.
