Walker currently stars alongside Tracy Letts and Annette Bening in ''All My Sons'' on Broadway.Benjamin Walker currently stars as Chris Keller in Arthur Miller's tense family drama ''All My Sons'' at the American Airlines Theatre. But nearly a decade ago, he had music, lyrics, and big set changes to contend with as the title character in Michael Friedman's rock musical ''Bloody Bloody Andrew Jackson''. As Walker learned all those years ago, when set changes depend on the lyrics you say, sometimes things can go awry. Fortunately, an audience will usually accept an apology and let you start again.Buy discount tickets to All My Sons here: http://bit.ly/AllMySonsTix
