Roger Daltrey of The Who: Rock legend, cancer warrior

“You’ll never make anything of your life, Daltrey”: Those words by the school principal who expelled Roger Daltrey for misbehavior at age 15 resonated enough to fuel the young man to one of rock’s most prestigious careers: Front man of The Who, star of “Tommy” and “Quadrophenia,” “mod” fashion icon, and cancer warrior. He talks with Jim Axelrod about his new memoir, “Thanks a Lot, Mr. Kibblewhite,” and about his 30-year mission of aiding hospital wards to deal with teenage cancer patients.
