Gibb's long battle with cancer ended on Sunday.
"The family of Robin Gibb, of the Bee Gees, announce with great sadness that Robin passed away today following his long battle with cancer and intestinal surgery," read the official statement announcing his death. Gibb, whose high-pitched vibrato was a defining feature of the Bee Gees' famous sound, had struggled with various forms of cancer and pneumonia for years. In January he described his condition in an interview in The Mail on Sunday: "For more than 18 months, I had lived with an inflammation of the colon; then I was diagnosed with colon cancer, which spread to the liver." He said his chemotherapy results had been "spectacular," but in April he was unable to attend the premiere of a score he'd written, The Titanic Requiem, indicating his health had taken a turn for the worse.
Made up of the English brothers Maurice, Barry and Robin Gibb, the Bee Gees were one of the most popular groups of all time. Their recordings throughout the '70s and '80s, most notably their contributions to the Saturday Night Fever soundtrack, earned them a slew of Grammys, induction to the Rock n' Roll Hall of Fame and CBEs (Commander of the Most Excellent Order of the British Empire). Maurice died in 2003, leaving Barry as the only surviving member of the group.
