Question: Who was a writer of a song on the album on the album "Children of the World" that also had a successful solo career?
Context: "You Stepped Into My Life" is a song released by the Bee Gees in September 1976 on the album "Children of the World".  It was also released as the B-side of "Love So Right".  Written by Barry, Robin & Maurice Gibb. The Allnighter is the second solo studio album by Glenn Frey, the guitarist and co-lead vocalist for the Eagles.  The album was released in mid 1984 on MCA in the United States and the United Kingdom, two years after Frey's modestly successful debut album, "No Fun Aloud" and four years after the demise of the Eagles.  It was and still is Frey's most successful solo album throughout his whole solo career, having reached #22 on the "Billboard" charts, and releasing two Top 20 singles with "Smuggler's Blues" and "Sexy Girl".  The album achieved Gold status by the RIAA in the US.  It is generally regarded as the culmination of the smoother, more adult-oriented sound of Frey's solo work. After the breakup of Led Zeppelin in 1980 (following the death of John Bonham), Robert Plant pursued a successful solo career comprising eleven studio albums, two compilation albums, three video albums, four collaborative albums and 42 singles.  He began his solo career with "Pictures at Eleven" in 1982, followed by 1983's "The Principle of Moments".  Popular tracks from this period include "Big Log" (a Top 20 hit in 1983), "In the Mood" (1984), "Little by Little" (from 1985's "Shaken 'n' Stirred"), "Tall Cool One" (a #25 hit off 1988's "Now and Zen"), "Manic Nirvana"'s "Hurting Kind (I've Got My Eyes on You)" (1990), and "I Believe" (from 1993's "Fate of Nations"), another song written for and dedicated to his late son, Karac.  In 1984, Plant formed a short-lived all-star group with Jimmy Page and Jeff Beck called the Honeydrippers, who had a #3 hit with a remake of the Phil Phillips' tune, "Sea of Love" and a follow-up hit with a cover of Roy Brown's "Rockin' at Midnight."  Although Plant avoided performing Led Zeppelin songs through much of this period, his tours in 1983 (with drummer Phil Collins) and 1985 were very successful, often performing to sold-out arena-sized venues. Laurenţiu Mocanu (born June 2, 1986), better known by his stage name Guess Who is a Romanian rapper.  He began his career as a member of the rap group Anonim along with group members Zekko and Griffo, and later launched a successful solo career in music.  He is one of the most successful artists from the new wave of Romanian hip hop and has gained considerable appreciation and mainstream attention in his native Romania following the release of his first solo album in 2009 called Probe Audio (Sound Check).  Guess Who gained popularity as a solo artist in 2007 when he leaked three tracks he had recorded for his solo album on the Internet.  The feedback was overwhelmingly positive and his cynical and ironic approach to writing quickly earned him a large fanbase.  Even though he repeatedly delayed for over two years releasing his first album, the Romanian audience received it well and he even gained attention from high level Romanian music executives when his video for the first single Tu (You) was aired on the Romanian music channel 1Music. Peter Kingsbery is an American singer songwriter who cofounded the band Cock Robin in the 1980s.  He grew up in Austin (Texas) where he studied classical music.  He moved to Nashville (Tennessee) where he began his career as a musician (he accompanied Brenda Lee on piano on a few tours) and then to Los Angeles at the end of the '70s where he began a career as a singer/songwriter.  He composed a few songs for Smokey Robinson, and one of his compositions, "Pilot Error", sung by Stephanie Mills, got some success in the dance charts in 1983.  At the beginning of the '80s, he founded the group Cock Robin with Anna LaCazio, Clive Wright and Lou Molino III which enjoyed great success in Western Europe mainly.  Failing to break their native country with a first self-titled album in 1985, the quartet became a duo of Kingsbery and LaCazio when they released their second album in 1987.  After the band split up in the early 1990s after a third album, Peter Kingsbery enjoyed a fairly successful solo career, releasing four albums over a decade, and scoring a major hit in France with the song "Only the Very Best."  With his fourth album he tried his luck singing in French, the language of his adopted country (living there since some years back). The Fleur de Lys (initially Les Fleur de Lys ["sic"]) were a British band originally formed in late 1964, in Southampton, Hampshire, England.  They recorded singles beginning in 1965 in the transitional Beat to psychedelic music genre, later known as freakbeat.  The band had varied line-ups; only drummer Keith Guster was a member throughout their history.  They finally disbanded in 1969.  Keyboardist Pete Sears went on to play with Sam Gopal Dream, and recorded on four early Rod Stewart albums including "Every Picture Tells a Story", and was a founding member of Jefferson Starship, going on to playing with Hot Tuna for ten years, and working with artists like John Lee Hooker, Dr. John, and Harvey Mandel, .  Bassist Gordon Haskell would eventually replace Greg Lake in King Crimson before going on a successful solo career.  Guitarist Bryn Haworth would move to the States and record an unreleased album under the name Wolfgang with a band including acclaimed bassist Leland Sklar.  He would record solo albums in the 1970s for Island Records and A&M Records, before continuing his solo career on Contemporary Christian Music labels. The Itals are a Jamaican reggae vocal group formed in 1976 by Alvin "Keith" Porter, Lloyd Ricketts, and Ronnie Davis (currently a member of The Tennors), all of whom had previously also recorded as solo artists.  All three had worked together in the late 1960s in The Westmorelites.  The group recorded several albums through the late 1970s and 1980s, with Ronnie Davis going on to a successful solo career in 1997 as Ronnie Davis and Idren.  The Itals' debut single, "In A Dis Ya Time", is regarded as the group's finest work, and topped the Jamaican chart.  1987's "Rasta Philosophy" was nominated for a Grammy Award as Best Reggae Album.  The line-up has changed over the years, with former solo artist David Isaacs joining in 1987 when Ricketts was sentenced to a prison term, preventing him from travelling to the United States.  Davis left the group in 1994, and was replaced by Porter's daughter Kada.  The Itals continued to tour in 2009 in support of the newly released "Let Them Talk".  In 2011 original member Lloyd Ricketts was able to obtain a work permit and performed two shows with Keith and Ronnie before his death.  Ronnie Davis stepped away from The Itals again in 2012 and reunited with the Rocksteady group The Tennors, but Keith continues to tour with two of his children, Darien Porter and Kada Porter, providing harmonies.  Keith will be releasing "Mind Over Matter", the remastered compilation of 22 early Itals songs and a solo album of reggae covers of classic R&B songs, called "Let's Get it On" in July 2015.

Following the group's name change to Labelle in the early 1970s, they released the iconic disco song "Lady Marmalade" and the group later became the first African-American vocal group to land the cover of "Rolling Stone" magazine.  After the group split in 1976, LaBelle began a successful solo career, starting with her critically acclaimed debut album, which included the career-defining song, "You Are My Friend".  LaBelle became a mainstream solo star in 1984 following the success of the singles, "If Only You Knew", "New Attitude" and "Stir It Up", with the latter two crossing over to pop audiences becoming radio staples.
