Seventeen
Club
Seventeen Club were comprised of Kimura Aki, Shibata Kumiko and Kudo Shizuka. They lasted only 2 singles before going their separate ways. Aki joined another group called B.C.G. and Kudo Shizuka joined the much larger Onyanko Club, then formed the splinter group Ushirogami Hiraretai (along with Saito Makiko and Ikuina Akiko) then set forth on her own to become one of the most popular Japanese idols of all time. The Seventeen Club singles are now some of the most sought after singles in the idol collectors circle. Quite rare indeed.
