Now Johnson has spoken for the first time about his injuries and treatment, saying he potentially still faces more surgery. In a Twitter post, he says: "I've had about 26 hours of surgery fixing my feet, legs and hip and might have another to go.

"I can't say how much all the support from my friends, family and strangers around the world has been. It means more to me than you will ever know. I've never been happier to be breathing. All the love."

Johnson adds that he won't go into detail about his bandmates' conditions, saying it's up to them to decide whether they want to make their own statements.
