Question: Harel Skaat was born on 8 August 1981, in Kfar Saba, Israel, to a family of Yemenite-Jewish and Iraqi-Jewish descent. When he was six years old, he won a national children's festival competition entitled "A Star for the Evening - Singing Big" in his hometown and while still a child he appeared in an episode of a popular Israeli television show called Parpar Nehmad (prpr nkhmd, Nice Butterfly). Throughout his youth, he continued to appear at festivals and television shows, and at the age of 15 he was the lead singer of both the Kfar Saba city band and his high school band. At 18, he sang with the Israel Defense Forces' Communications Corps.

In 2006, Skaat began a concert tour to promote his debut album, performing throughout Israel, including a concert at the Frederic R. Mann Auditorium in Tel Aviv (home to the Israel Philharmonic Orchestra). The tour eventually passed the 200 concert mark, an achievement which has been widely noted in the Israeli media. In 2009 Skaat began a second concert tour to promote the Dmuyot album. Reuters' music writer and critic, Assaf Nevo began his review of the launch of that tour by noting that if a computer were to create the ultimate Israeli pop singer it would resemble Skaat, who he wrote combined the charisma of Shlomo Artzi, the star quality of Ivri Lider, the vocal clarity of Izhar Cohen, the cuteness of Evitar Banai, and the sensitivity of Rami Kleinstein. While Nevo viewed Skaat as a good pop singer, he believed that Skaat's music did not extend beyond this genre.  Skaat has also frequently appeared at the Zappa night clubs in Tel Aviv and Herzliya, which regularly features live music from both Israeli and international musicians.  One of Skaat's first major appearances after Eurovision was on 28 July 2010 in Tel Aviv at a tribute to the French singer, Serge Gainsbourg. Skaat had been scheduled to perform at the opening ceremony of the XIX International Festival of Arts, "Slavianski Bazaar in Vitebsk" in Belarus on 9 July 2010, but his appearance was canceled by the organizers two days before the event. The organizers cited a need to downsize the number of concerts as a reason for the cancellation, but Israeli diplomatic sources alleged that the cancellation was due to political reasons and the Israeli ambassador to Belarus refused to attend the opening ceremony in protest. In March 2011, Skaat took part in a unique collaboration: singing three of his songs live in the Sharon Levi's Barcelona Dance Company's tap dance show, "Fragments", which debuted in Paris.

Problem: Helen Folasade Adu was born on 16 January 1959 in Ibadan, Oyo State, Nigeria. Her middle name, Folasade, means "honour confers a crown". Her parents, Adebisi Adu, a Nigerian lecturer in economics of Yoruba background, and Anne Hayes, an English district nurse, met in London, married in 1955 and moved to Nigeria. Her parents separated, however, and Anne Hayes returned to England, taking four-year-old Sade and older brother Banji with her to live with their grandparents near Colchester, Essex.

After completing a three-year course work in fashion design, and later modeling briefly, Sade began backup singing with British band Pride. During this time, she formed a songwriting partnership with Pride's guitarist/saxophonist Stuart Matthewman; together, backed by Pride's rhythm section, they began doing their own sets at Pride gigs. Her solo performances of the song "Smooth Operator" attracted the attention of record companies, and in 1983 Sade and Matthewman split from Pride, along with keyboardist Andrew Hale, bassist Paul Denman and drummer Paul Cook, to form the band Sade. By the time she performed her first show at London's Heaven nightclub, she had become so popular that 1,000 people were turned away at the door. In May 1983, Sade performed their first US show at the Danceteria nightclub in New York City. On 18 October 1983, Sade Adu signed with Epic Records, while the rest of the band signed in 1984.  Following the record deal, the group began recording their debut album, Diamond Life, which took six weeks to record and was recorded entirely at The Power Plant in London. Diamond Life was released on 16 July 1984, reached number two in the UK Album Chart, sold over 1.2 million copies in the UK, and won the Brit Award for Best British Album in 1985. The album was also a hit internationally, reaching number one in several countries and the top ten in the US, where it has sold in excess of four million copies. Diamond Life had international sales of over six million copies, becoming one of the top-selling debut recordings of the '80s, and the best-selling debut ever by a British female vocalist.  "Your Love Is King" was released as the album's lead single on 25 February 1984 and was a success in European territories, charting at number seven in Ireland and number six on the UK Singles Chart. The song was less successful in the US, where it peaked at number 54 on the US Billboard Hot 100. The third single, "Smooth Operator", was released on 15 September 1984 and became the most successful song in the US from the album Diamond Life. The track peaked at number five on the US Billboard Hot 100 and the US Billboard Hot Black Singles, as well as peaking at number one on the US Billboard Adult Contemporary chart. In Europe the song fared well, peaking at number 19 in the UK, and reaching the top 20 in Austria, Switzerland, France and Germany.
