<human>: 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. CANNOTANSWER
