Roger Daltrey says that making Tommy, the 1975 cinematic adaptation of the Who's rock opera, is what led to the creation of Teen Cancer America, an offshoot of U.K.'s Teenage Cancer Trust, a charity that supports hospitals in helping teenage patients.

"When we filmed it, we worked with lots and lots of extremely disabled people in some of the scenes, and some of them were very young," the singer tells Rolling Stone. "

It took me back to my teenaged years. I remember that dreadful period where you don't quite know who you are, where you're going. You're always insecure. In a way, you are deaf, dumb and blind to the world."

Daltrey and guitarist Pete Townshend recently hosted Who Cares About the Next Generation in Los Angeles, where the Who performed with Eddie Vedder.

"I just love to hear Eddie sing," Daltrey added. "I think he's got such a distinctive, fabulous voice.

He doesn't copy, so that's what I like; he does the Eddie Vedder version. It's never easy to do because most people will just try and copy what the Who have done. He's always himself."

Daltrey also reminisced about seeing the Beatles live in 1964.

"I remember not hearing one bloody note they played. The screaming was, like, the world's most ridiculous noise.

You heard the music for about two seconds, if that, and then it was just a barrage of high-pitched wails. And there was suddenly the smell of urine. Apparently Beatles fans used to wet themselves out of excitement."
