With Phil Spector producing, The Righteous Brothers had a huge hit with "You've Lost That Lovin' Feelin'
," which went to #1 in February 1965. That song Spector wrote with Barry Mann and Cynthia Weil, who were married. For the next single, Spector enlisted another husband-and-wife songwriting duo: Gerry Goffin and Carole King. They had been working with Spector for years, starting with a 1961 track for Gene Pitney called "Every Breath I Take." The trio came up with "Just Once In My Life," and Spector gave it his grand "wall of sound" production. It didn't do nearly as well as "You've Lost That Lovin' Feelin'," but the song was still a substantial hit.
