A spokesman for Bee Gee Robin Gibb said Sunday that the star has woken from a coma and is in improving health. Sixty-two-year-old Gibb fell into the coma last week. He has been in and out of the hospital over the past two years for treatment of unspecified stomach and colon ailments and told the BBC that he had a growth removed from his colon 18 months ago. Family members kept careful watch over Gibb as he remained in the coma for nearly two weeks. The singer opened his eyes Sunday and said hello to his 28-year-old son.
