Which Bee Gees song was their last number-one hit in the United States?

Love You Inside Out was the Bee Gees’ last number-one hit in the United States. Released in 1979, it topped the Billboard Hot 100 for one week in June, making it the group’s ninth—and final—U.S. number-one single.

The song appeared on Spirits Having Flown, the album that also produced “Tragedy” and “Too Much Heaven.” All three songs reached number one in the United States, an exceptional achievement that made the album one of the Bee Gees’ commercial peaks. “Love You Inside Out” followed “Tragedy” at the top of the chart and became the album’s third consecutive U.S. chart-topper.

The track has a slower funk groove than some of the group’s more overtly orchestral disco hits. Barry, Robin, and Maurice Gibb wrote it, with production by the Bee Gees, Albhy Galuten, and Karl Richardson. A common mix-up is choosing “Tragedy,” which was also a number-one hit, but it came earlier. “Spirits Having Flown” is the album title and a later single, not the final U.S. chart-topper.
