Robin Gibb in coma with pneumonia

Robin Gibb did not attend a concert last week due to pneumonia, his family said

Bee Gee Robin Gibb is in a coma after suffering from pneumonia, his official website says.

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.

"We are all hoping and praying that he will pull through," his website said.

In February, Gibb said he had been making a "spectacular" recovery from cancer but he was later readmitted 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 11 April, he did not attend the London premiere of his first classical work because of the pneumonia, his son said at the time.

The singer had also been due to perform a new song, called Don't Cry Alone, at The Titanic Requiem concert.
