The four brothers we know as the Gibbs – Andy, Robin, Maurice and Barry – were superstars of the 1970s, crooning legendary disco songs in unmatchable falsettos. Andy Gibb, went the solo route, while his three brothers formed the hit machine the Bee Gees. Today, only Barry Gibb remains; twins Maurice Gibb and Robin Gibb, who were born Dec. 22, 1949, died in 2003 and 2012, respectively. But the music the Gibb brothers created endures, reminding us of some of the grooviest times of our lives. Immerse yourself in that world again with our Brothers Gibb photo gallery.
