During the encore of their three-and-a-half-hour concert, during which they performed The River in its entirety for the first time since 2009 (the tour will go on for nine weeks), Bruce Springsteen and the E Street Band performed David Bowie’s classic Diamond Dogs track “Rebel Rebel.†The Boss talked about how Bowie, who died last week at 69, was an early advocate for the Jersey band way, way, way back in the very, very beginning (1973), even inviting Springsteen & Co. to the studio where Bowie was recording Young Americans. The cover, in classic Springsteen fashion, is neck-vein-bulging loud and features no fewer than three people playing the iconic riff. Doo doo doo-doo doo doo doo doo.
