full_context: Document 1: Marvin Gaye: Gaye was born Marvin Pentz Gay Jr. on April 2, 1939, at Freedman's Hospital in Washington, D.C., to church minister Marvin Gay Sr., and domestic worker Alberta Gay (née Cooper). His first home was in a public housing project, the Fairfax Apartments (now demolished) at 1617 1st Street SW in the Southwest Waterfront neighborhood. Although one of the city's oldest neighborhoods, with many elegant Federal-style homes, Southwest was primarily a vast slum. Most buildings were small, in extensive disrepair, and lacked both electricity and running water. The alleys were full of one- and two-story shacks, and nearly every dwelling was overcrowded. Gaye and his friends nicknamed the area "Simple City", owing to its being "half-city, half country".
Document 2: Detroit: The city has numerous neighborhoods consisting of vacant properties resulting in low inhabited density in those areas, stretching city services and infrastructure. These neighborhoods are concentrated in the northeast and on the city's fringes.

The survey also reported that most (86%) of the city's homes are in good condition with a minority (9%) in fair condition needing only minor repairs.

Document 10: Here, My Dear (song): "Here, My Dear" is a song written, composed and produced by American soul singer Marvin Gaye, issued on the album of the same name in 1978. The song was a sort of introduction to the deeply confessional and post-divorce concept that gave a chronological look back at the tempestuous marriage between Marvin and first wife Anna. The lyric, "You don't have the right to use a son of mine to keep me in line", became a memorable lyric for fans of Gaye and very much was a lyric attacking Anna for demanding alimony and child support payments to support then-twelve-year-old Marvin, III. Marvin then sarcastically told his wife that he dedicated the album to her but warned that she might "not be happy" and telling Anna "this is what you wanted" making a reference to the judge in their divorce case to give up royalties from this album to Anna. The song's musical background would be used for the song "Everybody Needs Love" from this album.
Document 11: Far Cry (Marvin Gaye song): "Far Cry" is the infamous unfinished recording that was included on singer Marvin Gaye's 1981 final Motown album, "In Our Lifetime". The song, essentially a funk-styled instrumental, featured a vocally conscious Gaye mouthing words while playing multiple instruments, including the drums and keyboards, on the first part of the song. The brief second half features a jazz instrumental with Gaye playing piano and drums and singing in falsetto, while his fellow instrumentalists, bassist Frank Blair and guitarist Gordon Banks, accompany him. The song's release among the eight original recordings on "In Our Lifetime" angered Marvin to the point where he severed ties with Motown, his home for twenty years, leaving the label for Columbia. As he told his biographer David Ritz, "I hadn't completed it...The song was in its most primitive stage. All I had was this jive vocal track, and they put it out as a finished fact. How could they embarrass me like that? I was humiliated. They also added guitar licks and bass lines. How dare they second guess my artistic decisions! Can you imagine saying to an artist, say Picasso, 'Okay, Pablo, you've been fooling with this picture long enough. We'll take your unfinished canvas and add a leg here, an arm there. You might be the artist, but you're behind schedule, so we'll finish up this painting for you. If you don't like the results, Pablo, baby, that's touch!'"
Document 12: Soldier's Plea: "Soldier's Plea" is a 1962 single released by singer Marvin Gaye as Tamla 54063, and was the last non-charted early single Marvin released prior to releasing his first hit single, "Stubborn Kind of Fellow", later that year.
Document 13: Algiers Motel incident: The Algiers Motel at 8301 Woodward Avenue near the Virginia Park district of Detroit was a black - owned business, owned by Sam Gant and McUrant Pye. It was one of three motels in Detroit owned by Gant and Pye, the others being the Alamo, at Alfred and Woodward, and the Rio Grande, on West Grand near Grand River. Prior to Gant and Pye's purchase in 1965, the motel's white owner had barred black people from staying at the motel. The Algiers was known to police as a center of drugs and prostitution and was raided regularly by the vice squad. It was located close to the then - headquarters of General Motors (GM) and executives of the firm were regular customers. To the rear of the motel, a three - story detached home, known as the Manor House or Annex, was also rented to clients. Its street address was 50 Virginia Park Street, and it was accessible from Virginia Park and through a driveway from Woodward. The motel itself was laid out in the shape of a ``U '', with its office, pool and cabana rooms to the left and a two - story wing of rooms to the right around its parking lot. The Manor House could be seen from Woodward Avenue.
Document 14: Falling in Love Again (Marvin Gaye song): "Falling in Love Again" is a 1977 song recorded by singer Marvin Gaye and issued on his 1978 album, "Here, My Dear" album. The song was another track on the personal album that did not discuss the demise of his first marriage. Instead of Anna Gaye, the song talked of the other woman in Marvin's life. Described in "You Can Leave, but It's Going to Cost You" as "that young girl", she was Janis Hunter, whom Gaye had married. In a solemn but still certain tone, he wanted to be sure that this time his love for Janis will be what he had always wanted. But as irony would have it, by the time of the album's release, Marvin and Janis' relationship was failing. By the end of the album's promotion, Janis had split from the singer after nearly two years as a married couple. They eventually divorced in February 1981. This song was the last song on "Here, My Dear" with a reprise from the album's "theme song", "When Did You Stop Loving Me, When Did I Stop Loving You", playing soon afterwards putting the album to a close for good.
Document 15: Anna's Song: "Anna's Song" is a song recorded by singer Marvin Gaye as part of his 1978 album, "Here, My Dear". Recorded during the midst of Marvin and estranged wife Anna going through an acrimonious divorce, the song autobiographically depicted several parts of Marvin and Anna's past including one lyric that hints at his first hit single, "Stubborn Kind of Fellow" where Gaye says ""What's it, husband, makes you so stubborn?"". A memorable part of the song for Marvin's fans includes a verse where Marvin's vocals rise when singing Anna's name. Unlike most of the songs on the album with the exception of "Sparrow", this song was recorded in a jazzy atmosphere.
