Roger Daltrey and Peter Townshend pledged Friday to raise money to renovate part of the Ronald Regan UCLA Medical Center pediatric floor into a separate space for patients ages 15 to 25.
Townshend was unable to appear in person in Los Angeles, but sent in a video message.
The effort is being supported by other celebrities including Robert Plant of Led Zeppelin. The goal is to create rooms clustered around a common lounge area where young cancer patients can hang out with one another.
Several hospitals across the country including St. Jude Children's Research Hospital and Children's Hospital of Philadelphia already have dedicated spaces for teen cancer patients.
