This 50th anniversary set devotes one disc apiece to a Brother Gibb, including non-Bee Gee little bro' Andy. Lovingly curated by Barry and Robin Gibb, Maurice's widow Yvonne, and Andy's daughter Peta, the booklet features testimonials from folks like Elton John, Tom Jones, Justin Timberlake, and Taylor Swift. But you don't need them to tell you what songs like "To Love Somebody," "I Started a Joke," and "I Just Want to Be Your Everything" amply demonstrate: too much pop heaven.
