The Bee Gees singer slipped into a coma earlier this month but regained consciousness at the weekend.
His wife Dwina told ITV News: “He is fantastic at the moment. He is laughing, he is joking, he is really happy. He just wants to get out.
“He has been very naughty because he pulled his feeding tube out so the nurses will have to put it back in again but he wants ice cream… he wants all kinds of things. It’s good anyway.
She added: “We played music to him for about ten days so we asked him if he wanted to listen to any more music and he said no.
“We’ve bombarded him with music for about ten days. It was very interesting…”
The singer’s son Robin-John Gibb added: “He woke up while we were playing the track which is a movement from the [Titanic] Requiem we have just written.
“He is completely compos mentis now and the first thing he said to me was ‘Hi R-J, can you tell them my back hurts?’ So we got a nurse to turn him. We said we loved each other.”
He continued: “Two days before that they said they’d thrown the kitchen sink at him, that it was time to make plans because he was in God’s hands and such.
“But he beats the odds again and they gave him an under 10% survival chance and he has beaten the odds… he really is something else.”
