Born in Brooklyn in 1947, Lambert began his career in 1960 when he signed to Capitol Records as a recording artist.  During the 70s, he and partner Brian Potter worked for the ABC-Dunhill label; however, Lambert’s songwriting and production work at ABC-Dunhill was beginning to make clear that his real fortune lay behind the scenes. He and Potter had their first taste of success writing for the Grass Roots in 1969, and struck gold penning Coven’s antiwar protest hit “One Tin Soldier” that year. A few more hits followed, including Gayle McCormick’s “It’s a Cryin’ Shame” and Hamilton, Joe Frank & Reynolds’ “Don’t Pull Your Love (Out).” 1972, however, was their true breakout year, thanks to their work on the Four Tops’ post-Motown LP Keeper of the Castle; the group went on to score hits with the Lambert/Potter-penned title track and “Ain’t No Woman (Like the One I Got),” which revived their career. In the wake of that success, Lambert and Potter were teamed with new ABC-Dunhill signee Dusty Springfield for 1973’s Cameo LP, and the following year they helped bring R&B group Tavares their first significant chart success. Lambert and Potter’s biggest smash as producers came in 1975 with Glen Campbell’s Rhinestone Cowboy LP, for which they also wrote four songs. By this point, Lambert and Potter had formed their own label, Haven, which was the mid-’70s home of the Righteous Brothers. Haven’s greatest commercial success came in 1978 with one-hit wonder Player’s “Baby Come Back,” produced but not written by Lambert and Potter. Lambert’s songwriting and production activity tailed off substantially in the ’80s, but he occasionally resurfaced to work with the likes of Natalie Cole and the Commodores.
