Tragedy! Bee Gees‘ singer Robin Gibb has died following a lengthy battle with cancer.

He was only 62.

The cause was complications of cancer and intestinal surgery, his family said in a statement.

Robin had been hospitalized for intestinal problems several times in the last two years. Cancer had spread from his colon to his liver, and in the weeks before his death he contracted pneumonia and for a while was in a coma.

Gibb’s musical career began when he formed the Bee Gees with his brothers Barry and Maurice in 1958.

The group is among the biggest-selling groups of all time with hits spanning six decades including Stayin’ Alive, How Deep Is Your Love, Massachusetts and Night Fever.

Robin’s twin brother, Maurice, died in 2003 from a twisted bowel. And younger brother Andy Gibb — who was not part of the group — died at 30 from a heart infection.

The only surviving member of the three Bee Gees is brother Barry, 65.
