Question: I Am My Brother's Keeper is a 1970 album by Motown vocalists and siblings David Ruffin and Jimmy Ruffin, an American soul singer, who had several hit records during what years, the most successful being the Top 10 hits "What Becomes of the Brokenhearted" and "Hold On (To My Love)"?
Context: Sunrise is an album by American soul singer Jimmy Ruffin, it was released in May 1980 and was produced by Robin Gibb (of the Bee Gees) and Blue Weaver.  The songs were co-written by Gibb either with Weaver and/or his brothers.  This album was released in US, Netherlands, UK, Norway and Germany.  The lead single "Hold On (To My Love)" reached top ten in UK and US. James Anthony Dean (7 February 1943 – 9 April 2006) was an American songwriter.  He was best known for his work at Motown Records in the 1960s, often in collaboration with William Weatherspoon with whom he co-wrote several hits including Jimmy Ruffin's "What Becomes of the Brokenhearted".  Dean also co-wrote, with John Glover, "You Don't Have to Be a Star (To Be in My Show)", a US no.1 hit for Marilyn McCoo and Billy Davis, Jr. David Ruffin is the self-titled album from singer David Ruffin.  Coming out after Motown refused to put out his proposed third album in 1971 (released as "David" in 2004), Ruffin was likewise no longer afforded access to "A-list" material and support musicians.  This album in many ways was a collaborative effort with Bobby Miller, who produced the album.  Miller also had a hand in composing eight of its tracks.  Although the album made it into the US R&B Top Five, it underperformed on the US pop charts, peaking at number 168.  Those slipping figures were indicators of the increasing lack of interest from Motown in Ruffin's career. "Gonna Give Her All the Love I've Got" is a 1967 Soul song, originally recorded and made a hit by Jimmy Ruffin on Motown's Soul Label imprint.  Ruffin's 1967 original version, from his album "Jimmy Ruffin Sings Top Ten", reached the Pop Top 30, peaking at #29, and was a Top 20 R&B Hit as well, peaking at #14.  It was also a hit in Britain, reaching #26 on the UK Singles Chart.  The song has a social context: it depicts a man anticipating his release from prison on the morrow, when he'll return home on a train to "the girl that I left behind," promising himself that he will reward her steadfast love for him by "giv[ing] her all the love [he's] got."  The song was written by Norman Whitfield and Barrett Strong and produced by Whitfield. Johnnie Mae Matthews (December 31, 1922 – January 6, 2002) was an American blues and R&B singer, songwriter, and record producer from Bessemer, Alabama.  Known as the “Godmother of Detroit Soul” and as the first African American female to own and operate her own record label (Northern Recording Company) she was an early influence on the careers of many of the now-famous recording stars who began their careers in Detroit, Michigan such as Otis Williams, David Ruffin, and Richard Street of the Temptations, Jimmy Ruffin, Joe Hunter of the Funk Brothers Band, Richard Wylie, Norman Whitfield, Berry Gordy, founder of Motown Records, Timmy Shaw, Barbara Lewis, Bettye LaVette and many more. "What Becomes of the Brokenhearted" is a hit single recorded by Jimmy Ruffin and released on Motown Records' Soul label in the summer of 1966.  It is a ballad, with lead singer Jimmy Ruffin recalling the pain that befalls the "brokenhearted", who had love that's now departed.  The song essentially deals with the struggle to overcome sadness while seeking a new relationship after a breakup. James Lee Ruffin (May 7, 1936 – November 17, 2014) was an American soul singer, and elder brother of David Ruffin of the Temptations.  He had several hit records between the 1960s and 1980s, the most successful being the Top 10 hits "What Becomes of the Brokenhearted" and "Hold On (To My Love)". The Choice Four were the most consistent of the male American soul/vocal groups produced by Van McCoy.  They were from Washington, D.C., recorded for RCA Records and had three albums.  Several of the group's members had previously sung in The Love Tones and The Stridels.  They had several minor hits on the "Billboard" charts in the mid-1970s.  Their attempt to hit big with their version of "When You're Young And In Love" was thwarted by the simultaneous release of a disco version of the song by actor Ralph Carter (of the "Good Times" TV show).  Their biggest hit, '"Come Down To Earth" became a favorite in the discos after the group had broken up.  They recorded the original version of the David Ruffin hit "Walk Away From Love" (also produced by McCoy), hitting the high note that Ruffin famously missed.  Both Pede "Pete" Marshall and Charles Blagmon went on to tour with groups led by former members of The Temptations after the group's demise, propr to its revival by Teddy Maduro. That's the Way Love Is is the tenth studio album by soul musician Marvin Gaye, released on January 8, 1970, on the Tamla (Motown) label.  Built on the success of the title track (#7 US Pop, #2 US R&B in late 1969) originally taken from "M.P.G.", and much like Gaye's "I Heard It Through The Grapevine" after its success, was released with intent to sell albums based on the success of one particular single (a Motown trademark).  Gaye was showing signs of disillusionment from the label's powers-that-be mentality but it didn't affect the singer's performance as he gave a powerful vocal in the title track and was especially impressive with his version of The Beatles' "Yesterday".  He achieved some success with a cover version of "How Can I Forget?"  (originally recorded by The Temptations), which just missed out on the US Pop Top 40, making #41, and reached #18 on the R&B Charts.  It's B-Side, a cover of Jimmy Ruffin's "Gonna Give Her All the Love I've Got", made a separate chart entry, and peaked at #67 and #27 on the Pop and Soul Charts respectively.  Gaye also recorded a version of Ruffin's "Don't You Miss Me a Little Bit Baby" for the album.  The LP also features Gaye's rendition of the socially conscious tune "Abraham, Martin & John", which became a hit in the UK, peaking at #9 in June 1970.  The single (and that of his duet single with Tammi Terrell titled "The Onion Song") is widely regarded as a hint of what would follow a year later with his "What's Going On".  He also covered The Temptations' hits "I Wish It Would Rain" and "Cloud Nine". I Am My Brother's Keeper is a 1970 album by Motown vocalists and siblings Jimmy Ruffin and David Ruffin, credited as "The Ruffin Brothers".  The album includes the singles "Stand by Me" and "When My Love Hand Comes Down".
