Bee Gee’s singer Robin Gibb is in a coma after suffering from pneumonia.
He has been recovering from cancer in recent months, but was too ill to attend a performance of his new work a few days ago.
His website said “We are all hoping and praying that he will pull through.”
In February, Gibb said he had been making a spectacular recovery from cancer but he was later re-admitted to hospital for intestinal surgery.
The message on his homepage added: “Because of this situation, Robin's website is temporarily unavailable. Sorry for any inconvenience.”
On the 11th of April, he did not attend the London premiere of his first classical work because of the pneumonia.
The singer had also been due to perform a new song, called Don't Cry Alone, at The Titanic Requi-em concert.
