Barry, Maurice and Robin Gibb-better known as the Bee Gees-are among the most successful vocal groups in rock and roll history. They rank sixth on the all-time top-sellers list, having sold 64 million albums to date. Only Elvis Presley, the Beatles, Michael Jackson, Garth Brooks and Paul McCartney have outsold the Bee Gees. The trio's contributions to 1977's Saturday Night Fever pushed that soundtrack album past the 40 million mark. It reigned as the top-selling album in history until Michael Jackson's Thriller-an album that Jackson has acknowledged was inspired by Saturday Night Fever-surpassed it in the Eighties. Saturday Night Fever and 1979's Spirits Having Flown combined to yield six #1 hits, making the Bee Gees the only group in pop history to write, produce and record that many consecutive chart-topping singles.
