The Who frontman Roger Daltrey is going blind and deaf

While The Who's Roger Daltrey still has what it takes to perform, the 81-year-old rock legend is dealing with some physical changes that are out of his control.

While performing alongside his bandmate Pete Townshend for the Teenage Cancer Trust charity event in London last week, Daltrey gave the crowd an unexpected health update. 

"The joys of getting old mean you go deaf. I also now have got the joy of going blind," he revealed mid-set, per Sky News.

"Fortunately, I still have my voice, because then I’ll have a full Tommy," he said, referencing the title character of The Who's 1969 album. "Deaf, dumb and blind kid."

During the set, Townshend, 79, also revealed he was recovering from a knee replacement. 

"Four and a half weeks ago, I had my left knee replaced," said Townshend, who injured his knee while dancing. 

Daltrey isn't the only musician who's recently suffered a hearing ailment.

"Quite suddenly I lost most of the hearing in my left ear, and nobody has an explanation for it. So, everything became more difficult," Simon previously told The Times in 2023.

"My reaction to that was frustration and annoyance; not quite anger yet, because I thought it would pass, it would repair itself."
