of the first song recorded as Chic was "Everybody Dance", which was on their first album. Under contract with Atlantic Records company, during 1977 they released the self-titled debut album Chic, which was an extension of the demonstration tape. But Edwards and Rodgers were convinced that to produce the band's recording studio sound when performing live with sound and visuals, they needed to add another female singer. Wright suggested her friend Luci Martin, who became a member during late winter/early spring of 1978. Soon after the sessions ended for the debut album, the band members began to work on Wright's self-titled debut solo album Norma Jean, released during 1978. This album included the successful nightclub song "Saturday". To facilitate Wright's solo career, the band had agreed to contract her with a separate record company. The legal details of this contract eventually forced Wright to end her relationship with the band during mid-1978, but she participated in the sessions for Chic-produced Sister Sledge album We Are Family (1979). She was replaced as a singer by Alfa Anderson, who had done back-up vocals on the band's debut album. For the Sister Sledge project, Edwards and Rodgers wrote and produced "He's the Greatest Dancer" (originally intended to be a Chic song), in exchange for "I Want Your Love" (intended originally to be performed by Sister Sledge). 1978–1979: "Le Freak" and "Good Times" The group endeavored to express "deep hidden meaning" in every song they wrote. During late 1978, the band released the album C'est Chic, containing one of its better-known tracks, "Le Freak". It was created in a jam session in Edwards' apartment, after they had failed on New Year's Eve 1977 to meet with Grace Jones at New York's nightclub Studio 54. The original refrain "Aaa, fuck off", intended for the doormen of Studio 54, was replaced that night with "Aaa, freak out", after trying a version with "Aaa, freak off". The resulting single was a great success, reaching No. 1 on the US charts and selling more than six million copies. It was the best-selling single album ever of Atlantic's parent company, Warner Music, until Madonna's "Vogue" in 1990. On March 21, 2018 "Le Freak" was selected for preservation in the National Recording Registry by the Library of Congress as being "culturally, historically, or artistically significant". The next year, the group released the Risqué album and the lead track "Good Times",
