Spirits Having Flown is the fifteenth album released by the Bee Gees. It was the group's first album after their collaboration on the Saturday Night Fever soundtrack. The album's first three tracks were released as singles and all reached No. 1 in the US, giving the Bee Gees an unbroken run of six US chart-toppers and tying a record set by The Beatles. It was the first Bee Gees album to make the UK top 40 in ten years (not counting the soundtrack for Saturday Night Fever), as well as being their first and only UK No. 1 album. It has sold 20 million copies worldwide.
