Daryl Hall and John Oates, often referred to as Hall & Oates, are an American musical duo from Philadelphia. Daryl Hall is generally the lead vocalist of the pairing. John Oates primarily plays electric guitar and provides backing vocals. The two write most of the songs they perform, either 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 sold an estimated 40 million records throughout their career, making them the third best-selling music duo of all time. (The Carpenters hold the top record with 150 million records sold.[citation needed]) Hall & Oates are best known for their six No. 1 hits on the Billboard Hot 100: “Rich Girl”, “Kiss on My List”, “Private Eyes”, “I Can’t Go for That (No Can Do)”, “Maneater”, and “Out of Touch”, as well as many other songs which charted in the Top 40. In total, they had 34 chart hits on the US Billboard Hot 100, seven RIAA platinum albums, and six RIAA gold albums. Because of that chart success, Billboard magazine named them the most successful duo of the rock era, surpassing The Everly Brothers. In terms of the UK charts, the duo have enjoyed moderate success with two UK top ten albums, spending a total of one-hundred and seventeen weeks in the UK top 75 album charts as well as eighty-four weeks in the top seventy-five of the UK Singles Charts.

In 2003, Hall and Oates were inducted into the Songwriters Hall of Fame. Billboard magazine had Hall & Oates at No. 15 on their list of the 100 greatest artists of all time and the No. 1 duo, while VH1 placed the duo as No. 99 on their list of the 100 greatest artists of all time. They were inducted into the Rock and Roll Hall of Fame in April 2014. On September 2, 2016 they received a star on the Hollywood Walk of Fame.
