After the failure of the Dawnbreakers, the two decided to play as a duo, with Seals on guitar, saxophone and violin and Crofts on guitar and
mandolin. They signed a contract with the record division of
Talent Associates (TA) in 1969 and released two
LPs, of which only the second reached the
Billboard 200 chart, peaking at No. 122 in October 1970. Crofts married fellow Dawnbreaker Billie Lee Day in 1969 and Seals married Ruby Jean Anderson in 1970. The pair signed a new contract with
Warner Bros. Records in August 1971. Their first album with their new label,
Year of Sunday, peaked at No. 133 in the US. Their second Warner Bros. album,
Summer Breeze, was a hit, peaking at No. 7 in 1972. The title cut was released as a single, peaking at No. 4 on the Adult Contemporary chart, and No. 6 Pop. The song "Hummingbird" was the second single released from the album, climbing to No. 12 AC, No. 20 Pop. The album has since been certified twice Platinum by the
RIAA for sales of two million copies in the US.{{cite book | first = Joseph | last = Murrells | year = 1978 | title = The Book of Golden Discs | edition = 2nd | publisher = Barrie and Jenkins Ltd | location = London | page = 320 | isbn = 0-214-20512-6 | url-access = registration In 1973 Warner Bros. released

We May Never Pass This Way (Again)", peaked at No. 21. The controversial
Unborn Child followed in 1974. Written shortly after
Roe v. Wade, Seals & Crofts expressed their anti-abortion position in the title song, which created a huge dilemma for radio stations. Some stations banned it while others added it to rotation. The album still went Gold despite the controversy and the lack of a Top 40 hit. The duo played at the
California Jam festival in
Ontario, California, on April 6, 1974. Attracting over 200,000 fans, the concert put them alongside 1970s acts such as
Black Sabbath;
Eagles;
Emerson, Lake & Palmer;
Deep Purple;
Earth, Wind & Fire;
Black Oak Arkansas; and
Rare Earth. Portions of the show were telecast on
ABC Television in the US, exposing the duo to a wider audience. 1975's ''
I'll Play for You was a Gold seller as well, featuring the No. 18 hit title track, and their multi-Platinum selling Greatest Hits'', released later the same year, has been certified 2× Platinum. The duo had a return to the singles chart with the song "
Get Closer", the title track from their 1976 album. Carolyn Willis (from the R&B vocal group
Honey Cone) appeared on the song and it peaked at No. 6 in July of that year. Willis also joined them for their 1976 tour, which resulted in the live album
Sudan Village. The pair also recorded songs that appeared in the feature films
One on One (1977) and ''
Foolin' Around (1980), as well as the song "First Years" that was the theme song to the debut (1978–79) season of the television series The Paper Chase''. 1978's ''
Takin' It Easy'' featured the two branching out and experimenting with other types of sounds, including the
disco influenced "
You're the Love", which reached No. 18. But their Gold selling days were behind them by this point. In 1979 they contributed to the album
Lote Tree, which was a narrated history of the
Baháʼí Faith that included songs by them and other artists. It was distributed only within Baháʼí media outlets.
The Longest Road, released in 1980, was their last for Warner Brothers. == Hiatus and reunions ==
