Spirits Having Flown, the 15th Bee Gees album, was released in January 1979, and was the group's first album following the massive success of 1977's multi-platinum Saturday Night Fever soundtrack. The first three tracks released from Spirits Having Flown - "Tragedy," "Too Much Heaven," and "Love You Inside Out" - all shot to No. 1 in the U.S., giving the Bee Gees an unbroken run of six U.S. chart-toppers in a one-year period.
