After guitarist Reichi "Chabo" Nakaido joined the band in 1978 replacing Haren, their popularity grew as they strengthened their rock and roll sound. Since then, they released series of milestone numbers including "Ameagari no Yozora Ni" (1980) and "Transistor Radio" (1980). in 1982, the band enter in part of a famous concert in 1982 called "The Day of R&B", which took place at a packed baseball stadium and included as headliners Chuck Berry and Sam Moore of Sam & Dave. The event was filmed and released as a video. Another thing in 1982 that helped establish them as a major act was a collaboration with Ryucihi Sakamoto called "Ikenai Rouge Magic". The single's jacket and promotional picture featured Imawano and Sakamoto kissing - quite a shocker at the time. The song was also used in a popular TV commercial. Among the best-known RC Succession songs are "Ameagari No Yozora Ni" and "Toranjisuta Rajio".

The album gained wide attention due to the incident, and debuted at number one of the Oricon album chart. The members Gee2Woo (keyboards) and Kozo Niida (drums) left the band in 1990. The remaining members Kiyoshiro, Nakaido, and Kazuo Kobayashi (bass) with some supporting musicians released the album Baby a Go-Go that year, but the band later announced that they would stop performing. The last concert was given at Nippon Budokan on December 25, 1990. After they stopped performing, Kiyoshiro and Nakaido continued
