Sir Elton John hasn't been able to do any Teenage Cancer Trust shows because of his Las Vegas residency.
The 71-year-old singer's husband David Furnish has fired back at Roger Daltrey's claims the 'Rocket Man' star has ignored requests to perform at the charity concerts.
Speaking to the Mirror, David said: "Elton was puzzled when that came out because every time Roger has asked, we have responded. The reason Elton has not been able to support is because he has been in Las Vegas doing his residency.
"And we've always got back to Roger. We had tremendous respect for the work that he's doing. When the requests have come in, Elton has always said: 'This is amazing. And I'd really like to support it when I have the time.'
The Who rocker Roger had said he supported Elton's AIDS Foundation three times in the past, but even this has been refuted.
David added: "Elton is a big, global star. He's now in the middle of a three-year farewell tour. We just can't stick him on a plane and move him around.
"But we've supported in other ways. Elton has actually done video announcements and things. We do what we can.
"The surprising thing was when Roger said he had been performing at our events, which is completely untrue."
He added that the pair haven't confronted Roger directly because they're "not that close", but he suggested maybe the musician was just in a bad mood when he made his original comments.
He said: "We're not that close. We reached out through mutual friends to say: 'Huh? We've always responded.'
"Maybe he was just having a bad day."
