Album Of The Week: Saturday Night Fever: The Original Movie Sound Track - Bee Gees & Various Artists (1977)
'How deep love Is Your Love' was released as a single in 1977. By the time 'Children of the World' was recorded, it was pretty much established that Barry Gibb was now the primary vocalist of the group, mostly being falsetto leads with the occasional natural breathy voice.
Even most of the backing vocals were done by Barry, such that Robin Gibb and Maurice Gibb are barely h...eard in the mix, even though they are there. Despite this, Robin sings the melody for the chorus and audibly sings various ad libs during this song.
