In 1959, Sedaka scored a hit with "Oh! Carol," written in her honor; King cut an answer record, "Oh! Neil," but it stiffed. She and Goffin, who eventually married, began writing under publishers Don Kirshner and Al Nevins in the famed pop songwriting house the Brill Building, where they worked alongside the likes of Doc Pomus, Mort Shuman, Jeff Barry, Ellie Greenwich and countless others. In 1961, Goffin and King scored their first hit with the Shirelles' chart-topping "Will You Love Me Tomorrow; " their next effort, Bobby Vee's "Take Good Care of My Baby," also hit Number One, as did "The Locomotion," recorded by their baby-sitter, Little Eva. Together, the couple wrote over 100 chart hits in a vast range of styles, including The Chiffons' "One Fine Day," The Monkees' "Pleasant Valley Sunday," The Drifters' "Up on the Roof," The Cookies' "Chains" (later covered by The Beatles), Aretha Franklin's "(You Make Me Feel) Like a Natural Woman" and The Crystals' controversial "He Hit Me (and It Felt like a Kiss)."
King also continued her attempts to mount a solo career, but scored only one hit, 1962's "It Might as Well Rain Until September." In the mid-1960s she, Goffin and columnist Al Aronowitz founded their own short-lived label, Tomorrow Records; Charles Larkey, the bassist for the Tomorrow group The Myddle Class, eventually became King's second husband after her marriage to Goffin dissolved. She and Larkey later moved to the West Coast, where in 1968 they founded the City, a trio rounded out by New York musician Danny Kortchmar. The City recorded one LP, Now That Everything's Been Said, but did not tour due to King's stage fright; as a result, the album was a commercial failure, although it did feature songs later popularized The Byrds' ("Wasn't Born to Follow"), Blood, Sweat and Tears ("Hi-De-Ho") and James Taylor ("You've Got a Friend").
Taylor and King ultimately became close friends, and he encouraged her to pursue a solo career. 1970's Writer proved a false start, but in 1971, she released Tapestry, which stayed on the charts for over six years and was the best-selling album of the era. A quiet, reflective work which proved seminal in the development of the singer/songwriter genre, Tapestry also scored a pair of hit singles, "So Far Away" and the chart-topping "It's Too Late," whose flip-side, "I Feel the Earth Move," garnered major airplay as well. 1971's Music also hit Number One, and generated the hit "Sweet Seasons; " 1972's Rhymes and Reasons reached Number Two on the charts, and 1974's Wrap Around Joy, which featured the hit "Jazzman," hit the Number One spot.
In 1975, King and Goffin reunited to write Thoroughbred, which also featured contributions from James Taylor, David Crosby and Graham Nash. After 1977's Simple Things, she mounted a tour with the backing group Navarro, and married her frequent songwriting partner Rick Evers, who died a year later after a heroin overdose. 1980's Pearls, a collection of performances of songs written during her partnership with Goffin, was her last significant hit, and King soon moved to a tiny mountain village in Idaho, where she became active in the environmental movement. After 1983's Speeding Time, she took a six-year hiatus from recording before releasing City Streets, which featured guest Eric Clapton. 1993's Colour of Your Dreams included a cameo from Guns N' Roses guitarist Slash; a year later, King made her Broadway debut in the drama Bloodbrothers. ~ Jason Ankeny, All Music Guide
