Robin Gibb in coma and fighting for his life His wife Dwina, brother Barry, 65, daughter Melissa, 37, and sons Spencer, 39, and Robin-John, 29 are understood to be keeping vigil at the private hospital. Gibb's twin brother and bandmate, Maurice, died from the same bowel condition that initially led doctors to operate on Robin. Their younger brother, Andy, who was not part of the Bee Gees, but a successful singer in his own right, died in 1988 from heart failure at the age of 30. The Bee Gees are best remembered for their contribution to the soundtrack of 1977 film Saturday Night Fever, which turned disco music into a worldwide phenomenon. Robin Gibb sang its theme tune, Stayin' Alive, as well as many of their greatest hits in the 1960s and 1970s, including Massachusetts, I've Gotta Get A Message To You, Lonely Days, How Can You Mend A Broken Heart and How Deep Is Your Love. Gibb last performed on stage in February, supporting injured servicemen and women at the Coming Home charity concert held at the London Palladium. He had been due to premier his classical work, The Titanic Requiem, this month with son Robin-John, but the event went ahead without him due to his poor health.
