IN: Daryl Hall and John Oates, often referred to as Hall & Oates, are an American musical duo. Daryl Hall is generally the lead vocalist; John Oates primarily plays electric guitar and provides backing vocals. The two write most of the songs they perform, separately or in collaboration. They achieved their greatest fame from the late 1970s to the mid-1980s with a fusion of rock and roll and rhythm and blues.

Hall and Oates have almost always toured extensively for each album release. But in 1985, the duo took a break after the release of their Live at the Apollo album with David Ruffin and Eddie Kendricks--voices of The Temptations and two of their heroes. This was RCA's second attempt at a live Hall and Oates album, following the 1978 release Livetime. Live at the Apollo was released primarily to fulfill the duo's contract with RCA, and contained a top-20 hit with a medley of "The Way You Do the Things You Do" and "My Girl", both hits Ruffin and Kendrick had recorded with the Temptations in 1964.  Hall and Oates had collaborated on the USA for Africa "We Are the World" project, with the former as one of the soloists and the latter as a chorus member, and performed at the Live Aid concert in Philadelphia, with Ruffin and Kendrick. The Hall and Oates band also backed up Mick Jagger's performance at this show.  Hall, Oates, Ruffin and Kendrick performed again at the MTV Video Music Awards in New York later that year, complete with an Apollo Theater-style marquee descending on the stage during their performance.  In May, 1985, Hall and Oates performed at the Nashville Municipal Auditorium. Just prior to Live Aid, on July 4, they participated in Liberty Concert, an outdoor benefit concert at Liberty State Park in Jersey City, New Jersey for the restoration of the Statue of Liberty. It became a major music event, drawing an estimated crowd of over 60,000 people.  In 1986, Daryl Hall scored a Top 5 US hit with "Dreamtime", from the album "Three Hearts in the Happy Ending Machine". That album also included the Top 40 hit "Foolish Pride" and the Top 100 hit "Somebody Like You," later performed by the duo live on their "Behind the Music" set. Although John Oates did not have a solo hit as a singer, he did receive credit as co-songwriter (with Iva Davies) of the 1988 Icehouse top 10 US hit "Electric Blue." Oates also worked as producer, co-songwriter and co-lead vocalist of the single "Love Is Fire" by The Parachute Club, which was a top 40 hit in Canada in 1987.

input: The elder Boulton's business prospered after young Matthew's birth, and the family moved to the Snow Hill area of Birmingham, then a well-to-do neighbourhood of new houses. As the local grammar school was in disrepair Boulton was sent to an academy in Deritend, on the other side of Birmingham. At the age of 15 he left school, and by 17 he had invented a technique for inlaying enamels in buckles that proved so popular that the buckles were exported to France, then reimported to Britain and billed as the latest French developments.  On 3 March 1749 Boulton married Mary Robinson, a distant cousin and the daughter of a successful mercer, and wealthy in her own right. They lived briefly with the bride's mother in Lichfield, and then moved to Birmingham, where the elder Matthew Boulton made his son a partner at the age of 21. Though the son signed business letters "from father and self", by the mid-1750s he was effectively running the business. The elder Boulton retired in 1757 and died in 1759.  The Boultons had three daughters in the early 1750s, but all died in infancy. Mary Boulton's health deteriorated, and she died in August 1759. Not long after her death Boulton began to woo her sister Anne. Marriage with a deceased wife's sister was forbidden by ecclesiastical law, though permitted by common law. Nonetheless, they married on 25 June 1760 at St. Mary's Church, Rotherhithe. Eric Delieb, who wrote a book on Boulton's silver, with a biographical sketch, suggests that the marriage celebrant, Rev. James Penfold, an impoverished curate, was probably bribed. Boulton later advised another man who was seeking to wed his late wife's sister: "I advise you to say nothing of your intentions but to go quickly and snugly to Scotland or some obscure corner of London, suppose Wapping, and there take lodgings to make yourself a parishioner. When the month is expired and the Law fulfilled, live and be happy ... I recommend silence, secrecy, and Scotland."  The union was opposed by Anne's brother Luke, who feared Boulton would control (and possibly dissipate) much of the Robinson family fortune. In 1764 Luke Robinson died, and his estate passed to his sister Anne and thus into Matthew Boulton's control.  The Boultons had two children, Matthew Robinson Boulton and Anne Boulton. Matthew Robinson in turn had six children with two wives. His eldest son Matthew Piers Watt Boulton, broadly educated and also a man of science, gained some fame posthumously for his invention of the important aeronautical flight control, the aileron. As his father before him, he also had two wives and six children.
