"The Longest Night" is a ballad number performed by the Bee Gees, with lead vocals by Robin Gibb.
The second time around, as it hits the second verse section, Robin goes off into a few lines of new melody as if he's been distracted by his thoughts.
Barry chimes in with his falsetto voice for backing vocals.
The musicians who played on this song were Barry Gibb and Nick Moroch on guitar, Maurice Gibb and Robbie Kondor on keyboards, drums programmed by Rhett Lawrence and Marcus Miller on bass.
