Fleetwood Mac released their eponymously titled studio album in 1975, which reached number one on the American charts. Buckingham contributed two songs to the album, "Monday Morning" and "I'm So Afraid", while also singing lead on "Blue Letter" and Nicks' song "Crystal". "I'm So Afraid" and "Monday Morning" were intended for the planned follow-up Buckingham Nicks studio album, but they were instead used with Fleetwood Mac. Despite the success of the new line-up's first studio album, it was their second studio album together, Rumours (1977), that propelled the band to superstar status, becoming one of the best-selling studio albums of all time. Buckingham's "Go Your Own Way" was the lead single, soaring into the US Top Ten; also on the album were Buckingham's "Second Hand News" and "Never Going Back Again". Buckingham also sang co-lead vocal on two of the band's biggest live staples: "The Chain", written by the entire band, and "Don't Stop", a Christine McVie number. After the resounding commercial success of Rumours (during the making of which Buckingham and Nicks broke up), Buckingham was determined to avoid falling into repeating the same musical pattern. The result was Tusk (1979), a double studio album that Buckingham primarily directed. Once again, Buckingham wrote the lead single, the title track that peaked at No. 8 on the Billboard Hot 100. Buckingham convinced Fleetwood to let his work on their next studio album be more experimental and to be allowed to work on tracks at home before bringing them to the rest of the band in the studio. It produced three hit singles: Lindsey Buckingham's "Tusk" (US No. 8), which featured the USC Trojan Marching Band, Christine McVie's "Think About Me" (US No. 20), and Stevie Nicks' 6½-minute opus "Sara" (US No. 7). "Sara" was cut to 4½ minutes for both the hit single and the first CD-release of the album, but the unedited version has since been restored on the 1988 greatest hits compilation, the 2004 reissue of Tusk and Fleetwood Mac's 2002 release of The Very Best of Fleetwood Mac. Original guitarist Peter Green also took part in the sessions of Tusk, although his playing on the Christine McVie track "Brown Eyes" is not credited on the album. It was during this time that Buckingham moved in with record company secretary and aspiring model Carol Ann Harris, with whom he lived until 1984. Though by most standards a hit,
