Context paragraphs:
Upside Down (Diana Ross song): "Upside Down" is a song written and produced by Chic members Nile Rodgers and Bernard Edwards.  It was recorded by American singer Diana Ross.  The song was issued as a single through the Motown label in 1980, as the lead single from her self-titled tenth studio album, "diana".  "Upside Down" hit number one on the "Billboard" Hot 100 chart on September 6, 1980.  It also hit number one on the "Billboard" Disco and Soul charts.  The single was released a full four weeks after the album was released.  It held down the number one spot for four weeks.

Diana (album): Diana (stylized as diana) is the tenth studio solo album by American singer Diana Ross, released on May 22, 1980 by Motown Records.  The album is the biggest-selling studio album of Ross's career, selling nine million copies worldwide and spawning three international hit singles, including the US number 1 hit "Upside Down".  All songs are composed, played and produced by Chic members Nile Rodgers and Bernard Edwards.

Workin' Overtime: Workin' Overtime is the seventeenth studio album by American singer Diana Ross, released on June 6, 1989 by Motown.  It was Ross' first Motown album since "Diana" (1980), after Ross left the label for a then record breaking $20 million deal with RCA.  Upon Diana's return to the label, Motown founder Berry Gordy, Jr. had sold the label to MCA Records and had positioned Jheryl Busby to the head of Motown.  Ross was at first reluctant to return to her old label but Gordy promised her a lot in her return: not only would Ross return to Motown as a recording act, but she would be the label's part-owner.  Ross reunited with collaborator Nile Rodgers to make this album - which was an attempt to gear her to a much younger audience bringing in new jack swing productions and house music.

Silk Electric: Silk Electric is a 1982 album released by American entertainer Diana Ross on the RCA label.  It reached #27 on the US "Billboard" 200 (#5 R&B), #33 in the UK Albums Chart and the top 20 in Sweden, Norway and the Netherlands.  The album cover was designed by Andy Warhol.  The album contains Ross' Top 10, Grammy-nominated single, "Muscles", which was produced and written by Michael Jackson.  All other tracks were produced by Ross.  The song "I Am Me" is incorrectly listed as written by Cindy Birdsong instead of Janie Bradford on the "Diana Ross Greatest Hits - The RCA Years" compilation album.  The album was certified Gold in the US and Silver in the UK.

A Brand New Day (The Wiz song): "A Brand New Day", also known as "Everybody Rejoice", is a song from the 1975 Broadway musical "The Wiz" written by American R&B singer and songwriter Luther Vandross.  (In 1976 Vandross recorded a version of the song for his album "Luther", on Cotillion Records.)  In the play, the song is sung to celebrate because Dorothy has killed Evilene, the tyrannical Wicked Witch of the West.  Dorothy, the Tin Man, the Cowardly Lion, and the Scarecrow sing the song with the newly freed Winkies, who were ruled and enslaved by Evilene.  It was later featured in the 1978 film version, sung by cast members Diana Ross, Michael Jackson, Nipsey Russell, and Ted Ross (credited as The Wiz Stars).  Given the all-Black cast of "The Wiz", the song's many references to freedom and new possibilities (especially as sung by African American characters who had just been freed from enslavement) certainly invoked the struggles and history of Blacks in America.  In the onscreen version of the song, Nipsey Russell can even be heard exclaiming "Free at last!" —a reference to civil rights activist Martin Luther King Jr. (His impromptu addition to the song is not heard on the soundtrack album version, instead replaced by sung vocals by Diana Ross.)

Together (The Supremes and The Temptations album): Together, released by Motown in 1969 (catalog number MS 692), was the second and final duets studio album combining Diana Ross & the Supremes and The Temptations into an eight-person Motown act.  Like the first duets LP, "Diana Ross & the Supremes Join The Temptations", it is composed almost entirely of covers, including versions of The Band's "The Weight", Sly & the Family Stone's "Sing a Simple Song", Frankie Valli's "Can't Take My Eyes Off You" (featuring Mary Wilson leading, in preparation for Ross' departure from the Supremes} and Motown songs like "Ain't Nothing Like the Real Thing" and "Uptight (Everything's Alright)".  "The Weight" was the only single in the US, and failed to make it into the American Top 40. " Why (Must We Fall in Love)", a UK exclusive single, was a Top 40 hit on the UK singles charts.

My Old Piano: "My Old Piano" is a song by American singer Diana Ross.  The song written and produced by Chic members Nile Rodgers and Bernard Edwards, was released as the third and final single in the United States, and the second single in the United Kingdom and other countries, from her tenth studio album, "Diana" (1980).

Up the Ladder to the Roof: "Up the Ladder to the Roof" is a 1970 hit single recorded by The Supremes for the Motown label.  It was the first Supremes single to feature new lead singer Jean Terrell in place of Diana Ross, who officially left the group for a solo career two weeks before the recording of this song in January 1970.  This song also marks a number of other firsts: it is the first Supremes single since "The Happening" in 1967 to be released under the name "The Supremes" instead of "Diana Ross & the Supremes", the first Supremes single solely produced by Norman Whitfield associate Frank Wilson, and the first Supremes single to make the United Kingdom Top 10 since "Reflections" in 1967.

I'm Coming Out: "I'm Coming Out" is a song made popular by American singer Diana Ross.  It was written and produced by Chic members Bernard Edwards and Nile Rodgers, and released on August 22, 1980, as the second single from Ross' self-titled tenth studio album "Diana" (1980).

He is the lead guitarist and co-founding member with Bernard Edwards of the band Chic, which has been active since 1976 and was one of the most successful groups of the disco era.
