Robin Gibb told doctors he "wants to live no matter what".
The Bee Gees' star has colon and liver cancer, and doctors feared he could die after he contracted pneumonia and slipped into a coma, but his wife Dwnia says he has never stopped fighting.
In an interview with The Sun, she said: "The doctors asked Robin if he wanted them to do everything in their power to save his life - or if he felt the time would come when enough was enough.
"He told them, 'There will never be a time when enough is enough. I want to live no matter what."
Robin astounded doctors by waking up from his coma earlier this week, and is now able to chat with his family, including brother Barry and son Robert-John and breathe with the aid of a mask.
