The Bee Gees' Robin Gibb is recovering from intestinal surgery over the weekend, which forced him to cancel commitments.
Questions of Gibb's health, who lives in the UK, were raised in April last year before it was revealed in November that he was battling liver cancer.
News on his recovery had been positive after a growth on his colon was removed, but this weekend surgery, announced by his publicist last night, has raised fresh concerns.
Robin is believed to have the same congenital defect as his late brother Maurice, who died aged 53 of a twisted intestine.

Robin's publicist said that due to the intestinal surgery, he had been forced to cancel a number of commitments.
Earlier this month Gibb told UK's The Sun newspaper that his illness was the price he paid for a life of fame.
“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,” he said.
“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.”
He added, “I've got a sense of urgency about life, rather than withdrawing from it and feeling depressed.”
He is currently working on – and scheduled to perform in April – his classic debut The Titanic Requiem, which he wrote with his son RJ. It will mark the 100th anniversary of the sinking of the ocean-liner.
