They weren't brothers, but Bill Medley and Bobby Hatfield (both born in 1940) were most definitely righteous, defining (and perhaps even inspiring) the term "blue-eyed soul" in the mid-'60s. The white Southern California duo were an established journeyman doo wop/R&B act before an association with Phil Spector produced one of the most memorable hits of the 1960s, "You've Lost That Lovin' Feelin'." The collaboration soon fell apart, though, and while the singers had some other excellent hit singles in a similar style, they proved unable to sustain their momentum after just a year or two at the top.

When Medley and Hatfield combined forces in 1962, they emerged from regional groups the Paramours and the Variations; in fact, they kept the Paramours billing for their first single. By 1963, they were calling themselves the Righteous Brothers, Medley taking the low parts with his smoky baritone, Hatfield taking the higher tenor and falsetto lines. For the next couple of years they did quite a few energetic R&B tunes on the Moonglow label that bore similarity to the gospel/soul/rock style of Ray Charles, copping their greatest success with "Little Latin Lupe Lu," which became a garage-band favorite covered by Mitch Ryder, the Kingsmen, and others.

Even on the Moonglow recordings, Bill Medley acted as producer and principal songwriter, but the duo wouldn't break out nationally until they put themselves at the services of Phil Spector. Spector gave the Wall of Sound treatment to "You've Lost That Lovin' Feelin'," a grandiose ballad penned by himself, Barry Mann, and Cynthia Weil. At nearly four minutes, the song was pushing the limits of what could be played on radio in the mid-'60s, and some listeners thought they were hearing a 45 single played at 33 rpm due to Medley's low, blurry lead vocal. No matter; the song had a power that couldn't be denied, and went all the way to number one.
