You've Lost That Lovin' Feelin'

"You've Lost That Lovin' Feelin'" is a song by Phil Spector, Barry Mann, and Cynthia Weil, first recorded in 1964 by the American vocal duo the Righteous Brothers and released as the lone single and title track from their 1965 album of the same name. This version, produced by Spector, is cited by some music critics as the ultimate expression and illustration of his Wall of Sound recording technique. The record was a critical and commercial success on its release, reaching number one in early February 1965 in both the United States and the United Kingdom. The single ranked No. 5 in Billboard's year-end Top 100 of 1965 Hot 100 hits – based on combined airplay and sales, and not including three charted weeks in December 1964 – and has entered the UK Top Ten on three occasions.

"You've Lost That Lovin' Feelin'" has been covered successfully by numerous artists. In 1965, Cilla Black's recording reached No. 2 in the UK Singles Chart. Dionne Warwick took her version to No. 16 on the Billboard Hot 100 chart in 1969. A 1971 duet version by singers Roberta Flack and Donny Hathaway peaked at No. 30 on the Billboard R&B singles chart. Long John Baldry charted at No. 2 in Australia with his 1979 remake and a 1980 version by Hall and Oates reached No. 12 on the US Hot 100.
