Listening to Roger Daltrey these days means hearing a lot of music.The Who singer is on the road singing the group's landmark 1969 rock opera "Tommy" with symphony orchestras. Last month, meanwhile, he released "As Long As I Have You," his first solo album in 26 years. Clearly the Rock and Roll Hall of Famer, who famously intoned "it's the singer not the song that makes the music move along" 46 years ago, is fully in gear these days.
