Context paragraphs:
Everybody Needs a Best Friend: "Everybody Needs a Best Friend" is a song from the 2012 feature film "Ted", with music composed by Walter Murphy and lyrics by Seth MacFarlane.  Performed by Norah Jones during the film's opening credits, the song was used as the film's main theme song.  It was released by Universal Republic Records on June 26, 2012.

Time to Get It Together: "Time to Get It Together" is a 1978 song recorded by Marvin Gaye and issued on Marvin's 1978 album, "Here, My Dear".  Much like "Everybody Needs Love", "Anger" and "A Funky Space Reincarnation", among others, this song doesn't discuss the demise of Marvin's marriage to Anna Gordy Gaye.  Instead the song is a biographical account of the singer's own personal demons as he battled drug abuse, paranoia and depression.

Everybody Needs Love (Marvin Gaye song): "Everybody Needs Love" is a 1977 song recorded by American soul singer Marvin Gaye and issued on the singer's confessional 1978 album, "Here, My Dear".  Though most of the songs on the album were based on a mostly antagonistic view of Marvin's first wife, Anna Gaye, a few songs like this stood out which discussed how everybody needed love.  Co-composed with "Let's Get It On" co-writer Ed Townsend, the song was based on a religious theme and was switched around by Marvin in certain areas including the lyrics "And my father/he needs love/that's true, baby/and I need love too" hinting at the tempestuous relationship between Marvin and his minister-father Marvin, Sr.  The song's musical background was also used to introduce the album on the title track.

Sunshine (Everybody Needs a Little): "Sunshine (Everybody Needs a Little)" is a song co-written recorded by American country music artist Steve Azar.  It was released in January 2010 as the second single from his album "Slide On Over Here".  Azar wrote the song with Jason Young.

Wishbone Four: Wishbone Four is the fourth studio album by British rock band Wishbone Ash, released in 1973.  It was a departure from their previous album, "Argus", in that it lacked that recording's overall cohesion and atmosphere and the loose conceptual framework of a stately, pastoral and warring medieval England.  Containing only hints of the extended twin-lead guitar harmonies, "Wishbone Four's" stylistic variety found its footing in acoustic folk elements in half of the eight-song set ("Ballad of the Beacon", "Everybody Needs a Friend", "Sorrel" and "Sing Out the Song"), two aggressive and melodic starters on each side of the vinyl release (Side 1: So Many Things to Say" and Side 2: "Doctor"), and the band's first use of horns on the semi-autobiographical "rave-up" touring song "No Easy Road".

Seth MacFarlane: Seth Woodbury MacFarlane (born October 26, 1973) is an American actor, filmmaker, comedian, and singer, working primarily in animation and comedy, as well as live-action and other genres.  MacFarlane is the creator of the TV series "Family Guy" (1999–2003, 2005–present) and "The Orville" (2017–present), and co-creator of the TV series "American Dad! " (2005–present) and "The Cleveland Show" (2009–2013).  He also wrote, directed, and starred in the films "Ted" (2012), its sequel "Ted 2" (2015), and "A Million Ways to Die in the West" (2014).

Everybody Needs Love (album): Everybody Needs Love is the 1967 debut album by Gladys Knight & the Pips and their first album for Motown Records' Soul imprint.  The LP, chiefly produced by Norman Whitfield, features the singles "Just Walk in My Shoes", the 1966 group's Motown debut, "Everybody Needs Love" and "I Heard It Through the Grapevine".

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.

Everybody Needs a Hero: "Everybody Needs a Hero" is a song recorded by American country music artist Gene Watson.  It was released in August 1987 as the second single from the album "Honky Tonk Crazy".  The song reached #28 on the "Billboard" Hot Country Singles & Tracks chart.  The song was written by Troy Seals and Max D. Barnes.

Everybody Needs Love (The Temptations song): "Everybody Needs Love" is a 1964 Motown song by Norman Whitfield and Edward Holland, Jr..  The first version released was by The Temptations for their album "The Temptin' Temptations" in 1965 (it also got airplay on some radio stations in the U.S.), but the most successful version was on a single by Gladys Knight & the Pips, which peaked at #39 on the "Billboard" Hot 100 chart, and #3 on the "Billboard" R&B singles chart, in 1967.  Other Motown acts that recorded this song were Mary Wells (who was the first to record it, though it was not released until after she left the company), which featured Eddie Kendricks of The Temptations in the background, Jimmy Ruffin, The Velvelettes, and The Miracles.  All versions of the song were produced by Whitfield.
