Jim Seals and Dash Crofts were both born in Texas, Seals in Sidney and Crofts in Cisco. They first met when Crofts was a drummer for a local band. Later, Seals joined an outfit called Dean Beard and the Crew Cats, where he played guitar; later on, Crofts joined Seals in the band. With Beard, they moved to Los Angeles to join The Champs, but the two did so only after the group's "Tequila" reached No. 1 in 1958. Seals also spent time during 1959 in the touring band of Eddie Cochran.
Seals had a composition ("It's Never Too Late") recorded by Brenda Lee in 1961, which featured as the B-side of her U.S. Billboard No. 6 single, "You Can Depend on Me". "It's Never Too Late" nevertheless reached No. 101 on Billboard and No. 100 on Cash Box (week ending 8 April 1961) in its own right. In the UK, the sides were switched when the single was released, but the single failed to make the UK singles chart (at that time only a Top 50 listing).
In 1963 Seals, Crofts, Glen Campbell and Jerry Cole left The Champs to form a band named "Glen Campbell and the GCs", which played at The Crossbow in Van Nuys, California. The band only lasted a couple of years before the members went their separate ways. Crofts returned to Texas and Seals joined a band named The Dawnbreakers (a reference to The Dawn-Breakers, a book about the beginnings of the Baha'i Faith). Crofts eventually returned to California to team up with Jim again, in The Dawnbreakers, and thus both Seals and Crofts were introduced to and became members of the Bahá'í Faith. After becoming longtime adherents of Baha'i, a number of their songs began to include references to and passages from Baha'i scriptures. When they appeared in concert, they often remained on stage after the performance to talk about the faith, while local Baha'is passed out literature to anyone interested.
