YOU'VE LOST THAT LOVIN' FEELING (The Righteous Brothers)

(From Wikipedia): "You've Lost That Lovin' Feelin'" is a 1964 song by The Righteous Brothers that became a number-one hit single in the United States and the United Kingdom the following year. In 1999, the performing-rights organization Broadcast Music, Inc. (BMI) ranked the song as having had more radio and television play in the United States than any other song during the 20th century. Additionally, the song was chosen as one of the Songs of the Century by RIAA and ranked #34 on the list of the 500 Greatest Songs of All Time by Rolling Stone.
The Righteous Brothers were the musical duo of Bill Medley and Bobby Hatfield. They recorded from 1963 through 1975 and continued to perform until Hatfield's death in 2003. Their emotive vocal stylings were sometimes dubbed "blue-eyed soul". Medley and Hatfield both possessed exceptional vocal talent, with range, control and tone that helped them create a strong and distinctive duet sound and also to perform as soloists. Medley sang the low parts with his deep, soulful baritone, with Hatfield taking the higher register vocals with his soaring countertenor. They adopted their name in 1962 while performing together in the Los Angeles area as part of a five-member group called The Paramours, which featured John Wimber (a founder of the Vineyard Movement) on keyboards. At the end of one particular performance, a U.S. Marine in the audience shouted, "That was righteous, brothers!", prompting the pair to adopt the name as they embarked on their duo career.

FEELINGS (Morris Albert)

From 'Wikipedia':
"Feelings" is a song written by Louis Gasté, also known as Loulou Gasté, and Brazilian singer Morris Albert and made famous by Albert, who recorded it as a single released in 1974 that later appeared as the title track of his 1975 debut album. The song's lyrics, recognizable by their "whoa whoa whoa" chorus, concern the singer's inability to "forget my feelings of love". Albert's original recording of the song was very successful, performing well internationally. "Feelings" peaked at #6 on the pop and #2 on the Adult Contemporary charts in America. Over the next few years "Feelings" was performed by many other vocalists including Ella Fitzgerald, Nina Simone, Angelica Maria, Petula Clark, José José, Caetano Veloso, Engelbert Humperdinck, Muslim Magomayev, Shirley Bassey, Glen Campbell, The O'Jays, Sarah Vaughan, Walter Jackson, Sergey Penkin, Julio Iglesias, Dobie Gray and Johnny Mathis. It was also recorded by numerous easy listening bandleaders and ensembles such as Percy Faith, Ferrante & Teicher, 101 Strings and Herb Ohta whose ukelele rendition was recorded with André Popp's orchestra for A&M Records.
In more recent years "Feelings" has been best known as a target of parody and ridicule for embodying what are perceived by many as the most insipid lyrical and musical qualities of 1970s "soft rock" music. It appears frequently on lists of "the worst songs ever" and was included on the 1998 Rhino Records compilation album '70s Party Killers.
In 1981, the French songwriter Loulou Gasté sued Morris Albert for copyright infringement, claiming that "Feelings" plagiarized the melody of his 1957 song "Pour Toi". They now share the credits of the song.
