To some, President Obama is the quinessential Chicago man. To others, it's Eddie Vedder. Thus, it made perfect sense for the Pearl Jam frontman to be one of the many distinct musicians to perform at the president's farewell address. Watch as Vedder takes on Neil Young's "Rockin' in the Free World," a Pearl Jam staple, and Patti Smith's "People Have the Power." Chicago Children's Choir lends an assist on the latter tune.
