Roger Daltrey has said he would rather perform on stage with his The Who bandmate Pete Townshend than anybody else.
The rocker is set to perform with Paul Weller and Kelly Jones at his Teenage Cancer Trust shows this year, and promises there will be "more surprises" at the concerts.
But he admitted he is keen to work with Pete again.
Roger said: "Ultimately, if I could sing with anyone, I'd rather sing with Pete. I'd be on stage with Pete over anybody."
He added: "We're talking about doing things, we have ideas, so that's good.
"Pete's needs are very different from mine. I need to work, I need to sing to keep my voice going, otherwise it'll stop doing what I want and disappear."
The 68-year-old singer joked that if he and Pete did reform again, they would have to be called Who's Left, as the rest of the original line-up for the band are no longer with us.
:: The Teenage Cancer Trust series of concerts begin at the Royal Albert Hall on March 28. For more information on the charity, go to www.teenagecancertrust.org.
