Singer Robin Gibb is fighting pneumonia in hospital and was too ill to attend the London premiere of his first classical work, The Titanic Requiem, his son said. He added that future hospitalisations were likely.
The 62-year-old founding member of the legendary group said in February that he had made a "spectacular" recovery from cancer, but had intestinal surgery last month. He was hospitalised late last year for stomach and colon problems.
Robin composed the symphonic Titanic Requiem with his son, Robin-John Gibb, and had been scheduled to perform a new song, Don't Cry Alone, in London last night. Robin's brother Barry is reported to be at the hospital.
