The band achieved several Top 40 hits throughout the latter half of the 1960s, including "It Ain't Me Babe" (1965), "You Baby" (1966), "Happy Together" (1967), "She'd Rather Be with Me" (1967), "Elenore" (1968), and "You Showed Me" (1969).

As the Turtles' commercial success waned by the end of the 1960s, they became plagued with management problems, lawsuits and conflicts with their label, White Whale Records, leading the group to break up in 1970.

After leaving Zappa at the end of 1971, Kaylan and Volman continued to perform under the Flo & Eddie name, becoming popular as a comedy rock act, and also went onto long-lasting success as session musicians.

With the help of KRLA and KFWB DJ and club owner Reb Foster, the Crossfires signed to the newly formed White Whale Records.

Adhering to the prevailing musical trend, the group rebranded itself as a folk rock band under the name the Tyrtles, an intentionally stylized misspelling inspired by the Byrds and the Beatles.

[5] Because of the stylistic change from "Surf music" to "Folk rock", Kaylan and Volman dropped the saxophones to become the band's vocalists.

"It Ain't Me Babe" reached the Billboard Top 10 in the late summer of 1965, and was the title track of the band's first album.

[5] "Happy Together", the first of several key Turtles singles co-written by Garry Bonner and Alan Gordon, had been rejected by countless performers.

"Happy Together", both their biggest hit and their signature song, signaled a turning point for both the Turtles and for Chip Douglas, who provided the arrangement.

[7] This same year saw the Turtles performing the title song (composed by John Williams with lyrics by Leslie Bricusse) for the Twentieth Century-Fox bedroom farce A Guide for the Married Man.

By the end of 1967 the band were reduced to a five-piece, when rhythm guitarist Jim Tucker departed, citing the pressure of touring and recording new material.

Towards the end of 1969, the group released its next album, Turtle Soup, a critically well-received LP produced by Ray Davies of the Kinks.

In spite of Turtle Soup's positive reception from the music press, its commercial success was marginal, and the band began to disintegrate.

Long disillusioned with their record label and its growing financial problems by this time, Kaylan and Volman resisted White Whale's efforts to turn the Turtles into something approaching an assembly-line pop act, like the early Monkees.

With the demise of the Turtles, White Whale Records lost its biggest moneymaker, had few commercially viable bands, and soon ceased operations.

[5] Volman and Kaylan sang backing vocals on several recordings by the band T. Rex, including their worldwide 1971 hit "Get It On (Bang a Gong)" and the albums Electric Warrior and The Slider.

In the mid-1970s, Volman and Kaylan started their syndicated radio show titled Flo & Eddie by the Fireside, which originated from KMET in Los Angeles.

In 1980, Flo and Eddie performed backing vocals on Alice Cooper's Flush the Fashion and sang backup on Bruce Springsteen's "Hungry Heart" from his album The River.

In 1983, they also contributed backing vocals to the self-titled debut album of British New wave band Espionage, produced by Roy Thomas Baker and released by A&M Records.

[10] In 1987, Kaylan and Volman appeared in a music video of their 1967 song "Happy Together" to promote the romantic comedy Making Mr.

That year also saw the debut of the previously unreleased Shell Shock album, as well as a new retrospective CD 20 Greatest Hits, both released by Rhino.

The 1989 debut album by hip hop combo De La Soul, 3 Feet High and Rising, featured an uncredited sample from the Turtles (specifically, the introduction to "You Showed Me"), in the song "Transmitting Live from Mars."

In 2018, since Kaylan required heart and back surgery, he was told by his doctors to cease touring, so Ron Dante (a prolific session musician of the Archies, the Cuff Links and the Detergents fame) replaced him.
