"Decades: The Bee Gees in the 1970s" is the latest volume in a series of books covering the entire career of the Brothers Gibb and documenting every album and song. Two of the three authors, Andrew and Grant, return to the podcast for the first of a two-part chat about the the early part of that decade and how the Bee Gees found their mojo again after the acrimonious split of the late 1960s.
