He may not have been the flashiest member of the Gibb clan (that honor goes to baby brother Andy, a teen idol who died tragically at 30) or the most prolific (see oldest brother Barry, oft-dubbed the second-most-successful songwriter in history, after Paul McCartney). But to countless fans, Robin Gibb — who passed away May 20 in London at age 62 after a long cancer battle — was an integral, inimitable voice in pop music. Born in the U.K. and raised in Brisbane, Australia, Robin shared the frontman role when he, fraternal twin Maurice, and Barry formed the Bee Gees in the late 1950s (sibling rivalry for the spot was ongoing). Barry largely led the songs that immortalized them as disco superstars, especially on 1977’s era-defining Saturday Night Fever. But it was Robin’s sweet, tremulous tenor that anchored late-’60s classics like ”I Started a Joke” and ”Holiday.” More hits followed the trio’s Fever prime, though their fame faded somewhat as the disco craze waned, and Robin focused on solo work as well as songwriting and production for other artists. He leaves his wife, Dwina, four children, and the last surviving Gibb brother, Barry, 65.
