Love him or hate him, Bruce Springsteen is notorious for his dedication to his audiences, performing his guts out for hours on end through thousands of shows over the course of a 50-plus year career. The average Springsteen concert is longer than the average professional football game, and regularly goes far longer. His longest show ever was four hours and six minutes long, an overseas affair. His longest U.S. concert was in Philadelphia and clocked in at four hours and four minutes. Easy to do when you start out in your teens, right? Not so fast. Bruce knocked out those 244 minutes last October, less than a year shy of his 70th birthday.
