4/7. Stuart Maconie recalls critical and defining moments in popular music. He continues with the late 1979 release of the Sugarhill Gang's Rapper's Delight, which is credited as the first rap record to enter Billboard's Hot 100. The Harlem trio's single - which samples Chic's Good Times and is markedly good-natured and attitude-free by modern rap standards - reportedly sold more than eight million copies worldwide while peaking at number 36 in the US pop charts. A top three hit here in the UK, it proved to be not just a novelty record as claimed by many in the music industry, instead kick-starting a rap (and later hip-hop) revolution.
