The Who rocker Roger Daltrey has fired back at critics who savaged his 2010 Super Bowl performance, revealing he underwent surgery to remove a pre-cancerous growth from his throat just weeks before the big concert.
The My Generation singer was heavily criticised for failing to hit the high notes during The Who's half-time show - and now he's explaining why he may not have been on top form.
In a CBS TV interview in America at the beginning of December (10) Daltrey revealed his voice wasn't "performing in a normal way" and friends put him in touch with master throat surgeon Steven Zeitel in Massachusetts in late 2009.
Daltrey says, "It was becoming hard work to sing... He (Zeitel) saw me and told me that he didn't like what he saw."
One week before Christmas in 2009, Daltrey went under the knife, according to RollingStone.com.
The rocker adds, "He took off what he could from the problem area on my vocal cord. He said it wasn't cancer, but it was pre-cancerous, and you have to keep an eye on it.
"(Now) I see him every time after I finish a tour and he swears that he'll keep me singing into my 80s. That might upset some people, but it keeps me happy."
