Robin Gibb was making a ''bucket list'' before he fell into a coma.
The 62-year-old Bee Gees star - who had just achieved remission from colon and liver cancer - was drawing up a list of things he wanted to achieve in the rest of his life.
But the singer took a turn for the worse after being struck down with pneumonia last week, and now has friends and relatives, including wife Dwina, and son Robin-John, 29, keeping a bedside vigil amid fears he has just days to live.
A source said: ''He has kept an antique notebook by his bed to write down lyrics and ideas he has had floating around.
''He has also expressed a desire to set up a children's charity involving music. It was a ''bucket list'' of things he wanted to achieve. But everyone is very worried now.
''His family are taking it hour by hour, praying for a miracle. But with Robin they know never to give up.''
Speaking about the fast deterioration of Robin's health, a second insider described the situation as ''devastating''.
The source told the Daily Mirror: ''His spirit has been shattered since the pneumonia and he has gone visibly downhill. Before he slipped into a coma he was struggling to get out of bed without a wheelchair.''
Robin underwent seven rounds of chemotherapy after being diagnosed 18 months ago, and previously admitted he wonders if his family tragedies - including the deaths of his brothers Andy in 1988 and Maurice in 2003 - are a ''karmic price'' for the band's worldwide success.
He said: ''I sometimes wonder if all the tragedies my family has suffered, like Andy and Maurice dying so young and everything that's happened to me recently, is a kind of karmic price we are paying for all the fame and fortune we've had.
''But we've worked hard for everything we've achieved.
''I am not and never have been at death's door. But the illness, and the untimely death of my brothers, has made me conscious of the fact that - rather than just think about it - it's crucial that you do today what you want to do.
