"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," his spokesperson said in a statement obtained by the magazine. "The family have asked that their privacy is respected at this very difficult time."
Gibb was diagnosed with liver and colon cancer two years ago, but despite what he called a "spectacular recovery," his doctor confirmed he was suffering from advanced stage colorectal cancer in April. Gibb also battled pneumonia, earlier this year, which put him into a coma.
Gibb was born in England in 1949, the twin of Maurice Gibb. The family moved to Australia in 1958, and Robin and Maurice soon began singing with their older brother, Barry. The trio hosted a weekly variety show down under and hit it big when they returned to England and signed with famous manager Robert Stigwood. After their first rise to fame, the brothers split and Robin went solo. They got back together in the early '70s and became household names across the world thanks to their contributions to the Saturday Night Fever soundtrack, which included hit songs like "Stayin' Alive" and "You Should Be Dancing."
The Bee Gees were inducted into the Rock and Roll Hall of Fame in 1997 and released their last album, This Is Where I Came In, in 2001. The group called it quits two years later when Maurice died of complications from a twisted intestine, which Robin underwent surgery for in 2010.
More recently, Robin had collaborated with his son, Robin-John, on The Titanic Requiem, a mix of orchestral and vocal pieces telling the story about the doomed ship. The work premiered on April 10 in London.
In pop culture, Justin Timberlake was known for playing Robin Gibb to Jimmy Fallon's Barry Gibb in the popular recurring SNL sketch, "The Barry Gibb Talk Show." Last month, Glee performed some of the band's biggest hits from the Saturday Night Fever soundtrack in the episode "Saturday Night Glee-ver."
