Question: You've Lost That Lovin' Feelin' was co-written by the wife of which other songwriter?
Context: William Thomas "Bill" Medley (born September 19, 1940) is an American singer and songwriter, best known as one half of The Righteous Brothers.  He is noted for his bass-baritone voice, exemplified in songs such as "You've Lost That Lovin' Feelin'".  Medley produced a number of the duo's songs, including "Unchained Melody" and "Soul and Inspiration". Cynthia Weil (born October 18, 1940) is a prominent American songwriter.  She is famous for having written many songs together with her husband Barry Mann. "You've Lost That Lovin' Feelin'" is a song written by Phil Spector, Barry Mann, and Cynthia Weil.  It was first recorded by the Righteous Brothers in 1964, and was produced by Phil Spector.  Their recording is considered by some music critics to be the ultimate expression and illustration of Spector's "Wall of Sound" recording technique.  It has also been described by various music writers as "one of the best records ever made" and "the ultimate pop record". What a Feelin' is the second album by American singer-songwriter Irene Cara and her most successful album to date.  Released in November 1983, this album is dominated by dance-pop and Euro disco songs produced by the legendary producer Giorgio Moroder, unlike her R&B-heavy debut.  Many of the songs were co-written by Cara herself.  The album includes the major hit singles, "Dream (Hold On to Your Dream)" (U.S. #37), "Flashdance... What a Feelin'" (her only #1 hit in the U.S.), "Why Me? " (U.S. #13), "You Were Made for Me" (U.S. #78) and "Breakdance" (which was her third and last Top 10 single in the U.S., reaching #8). "(You're My) Soul And Inspiration" is a song by American pop duo the Righteous Brothers.  It was the group's first hit after leaving their long-time producer Phil Spector.  The song was written by Barry Mann and Cynthia Weil, who also wrote the group's first hit "You've Lost That Lovin' Feelin'" along with Phil Spector.  It is the title track of their album.  The single peaked at No. 1 on the US "Billboard" Hot 100, and reached No. 15 on the UK Singles Chart.  "Billboard" ranked the record as the No. 3 single for 1966. The Firm is the first studio album by the British rock band The Firm, released by Atlantic Records on 11 February 1985.  Tracks ranged from the epic "Midnight Moonlight" based on a previously unreleased song by Led Zeppelin called "Swan Song", first tinkered with during the "Physical Graffiti" sessions, to the commercially successful "Radioactive".  "Closer" employs a horn section to subtle effect.  It also includes the Righteous Brothers' hit "You've Lost That Lovin' Feelin'" with the fretless bass sound of Tony Franklin. The Hits Chapter 1 is the first greatest hits album released by American country music artist Sammy Kershaw.  It was issued in 1995 (see 1995 in country music) on the Mercury Records label.  The album comprises the ten greatest hits from his first three studio albums: four each from 1991's "Don't Go Near the Water" and 1993's "Haunted Heart", plus two more from 1994's "Feelin' Good Train".  Also included are "Still Lovin' You" (the third track from "Haunted Heart", never released as a single) and the new track "Your Tattoo", which was released as a single in 1995 and peaked at #47 on the country charts.  "The Hits Chapter 1" earned a gold certification from the RIAA for shipping 500,000 copies in the United States. How Do You Say I Don't Love You Anymore was Freda Payne's second American album (following a release in Sweden with Don Gardner) released May 28, 1966.  although regarded primarily as a jazz album, there are also several covers of pop songs featured, including the Beatles' hit "Yesterday," "Let It Be Me," the Righteous Brothers' "You've Lost That Lovin' Feelin'," "Feeling Good," and "If You Love Me (Really Love Me)." To capture the sensation of teen-idol Shaun Cassidy, Warner Bros.  Records released a live album of his 1979 concert tour named That's Rock 'N' Roll Live.  The album featured tracks from his four studio albums ("Shaun Cassidy", "Born Late", "Under Wraps" and the then-forthcoming album "Room Service").  The album also featured a cover of The Righteous Brothers' hit song, "You've Lost That Lovin' Feelin'". John William "Long John" Baldry (12 January 1941 – 21 July 2005) was an English blues singer and a voice actor.  He sang with many British musicians, with Rod Stewart and Elton John appearing in bands led by Baldry in the 1960s.  He enjoyed pop success in the UK where "Let the Heartaches Begin" reached No. 1 in 1967 and in Australia where his duet with Kathi McDonald "You've Lost That Lovin' Feelin'" reached number two in 1980.  Baldry lived in Canada from the late 1970s until his death; there he continued to make records and do voiceover work.  Two of his best known roles in voice acting were as Dr. Robotnik in "Adventures of Sonic the Hedgehog", and as KOMPLEX in "Bucky O'Hare and the Toad Wars.
