However, the GS boom peaked in 1968 and began to died down with upcoming rhythm and blues, hard and soft rocks, funky, and disco during the early 1970s. The next single "My Baby" was released in October, and even with Takano's singing reminiscent of the early singles, it did not become a hit. On March 1969, the Beatles' "", which is famous for its marmalade rhythm, was released with the translation of Kenji Sazanami for the first time. However, in April, vocalist Usui left the group, and Paul Okada, who was in another GS, joined them. The song they released was "Teltel Heaven".
