"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," says a statement released by the family's spokesperson. "The family have asked that their privacy is respected at this very difficult time."
Gibb has had a history of health problems stemming from a 2010 liver and colon cancer diagnosis. Though Gibb had recovered from his first bout with the disease, another tumor recently surfaced in conjunction with pneumonia, leaving him in a coma at a London hospital in mid-April. Gibb's wife Dwina and brother Barry stayed by his side, singing to the ailing star in an effort for him to regain consciousness.
Gibb did awaken from his coma in late April and was able to speak with his family members, though he was still reliant on an oxygen mask and intravenous feeding.
"Robin's wife, Dwina and son, Robin-John, his son Spencer and daughter Melissa have been at his bedside every day, talking to him and playing his favorite music to him," Gibb's doctor, Dr. Andrew Thillainayagam said in April. "They have been tireless in their determination never to give up on him."
Robin and his brothers, Barry and Maurice (who died in 2003 due to complications from a twisted intestine), formed The Bee Gees in the late 1960s. The group was inducted into the Rock and Roll Hall of Fame in 1997 with hits like "Stayin' Alive," "How Deep Is Your Love" and "I Started A Joke."
