Robin Gibb’s wife Dwina keeps vigil at his bedside in a private hospital in Chelsea, West London, UK, where the Bee Gee continues to fight for his life.
Robin Gibb, 62, has been in a coma since Friday, and doctors fear he has just days to live.
Bee Gees star is now battling pneumonia, following months of health troubles.
Robin Gibb was diagnosed with colon cancer after surgery for a blocked bowel in 2010, with the disease later spreading to his liver.
His latest setback comes after a series of operations and treatments, and amid reports of a new tumor.
Dwina Gibb, his children and Robin’s brother, Barry, have been praying at his bedside.
Robin Gibb’ son, Robin-John, 29 – known as RJ for short – said he would do “anything” to have his father make a swift and full recovery.
RJ said: “My dad has had a hard recovery from cancer.
“When you get rid of the cancer a lot of periphery problems can occur. This is so sad.”
RJ told The People that everyone from the family was “praying” for a recovery and that he felt honored to be living in his father’s shadow.
He added: “If people say that I’m living in my ¬father’s shadow, all I can say is what a great shadow that is to be living in.”
Robin Gibb made a recovery from liver and colon cancer this year, but doctors believe a second tumor may be present.
He has also developed pneumonia.
Robin Gibb revealed his battle with cancer in October 2010.
He had emergency surgery to treat a blocked bowel, before a further operation to treat a twisted bowel. Colon cancer was then discovered and it spread to his liver.
Robin Gibb’s twin brother Maurice died of complications resulting from a twisted intestine in 2003, aged 53.
