The surviving Who are old. They refuse to die. But it's not for lack of trying. They nearly killed themselves during a brilliant, cathartic two-hour concert for a nearly 10,000 fans at Toyota Center on Saturday. The remaining two — Pete Townshend and Roger Daltrey — are promoting the first Who album in more than two decades, "Endless Wire." There is something to prove beyond "My Generation's" defiant prayer. And it is so powerfully executed that it's irresistible on its merits — and not just in memory. Old and new songs came passionately alive onstage with the help of drummer Zak Starkey, guitarist Simon Townshend (Pete's brother), bassist Pino Palladino and keyboardist John Bundrick.
