The Bee Gees "Britain's first family of harmony", were a group formed in 1958, with their lineup having comprised brothers Barry, Robin, and Maurice Gibb. The trio were successful for most of their 5 decades of recording music, with two periods of exceptional success, first as a popular music act in the late 1960s and early 1970s, then as top performers of the disco music era in the mid-to-late 1970s.
