DO UP: Ai ING / Shower 7-inch EP Record 7-inch single "DO UP: Ai ING", B-side is "Koi no Vacance NO.1". - Title: DO UP: Ai ING Debut single of 80s idol group featuring Rikako Murakami and Yumi Yano This group anticipated the history of idol groups like Onyanko Club, Morning Musume, and AKB, feeling like they were ahead of their time. This is the debut single from "Shower," a large 7-member idol group from 1982, which could be considered a precursor to Onyanko Club. The group included RIKAKO (Rikako Murakami), who was only 15 years old at the time. Yumi Yano, who later re-debuted as a solo artist, was also a member. Both A and B sides of the songs were produced by Yasunori Soryo. The coupling features the pop tune "DO UP: Ai ING," which is reminiscent of oldies, and the teen pop song "Koi no Vacance NO.1," both of which are quite good. Record surface has no noticeable scratches or stains. Please consider this item if you understand that it is a used record and may show signs of aging. Thank you for looking.
