Musicians and celebrities are some of the most popular subjects on YouTube, and a new video is tapping that star power to mobilize young voters for Barack Obama. On Saturday, YouTuber user “WeCan08” uploaded “Yes We Can,” a music video for a new Obama ballad by the Black Eyed Peas’ will.i.am and director Jesse Dylan, Bob Dylan’s son. The “song” was essentially written by Barack Obama, since the lyrics are adapted from his “Yes We Can” speech after the New Hampshire primary. That speech, of course, was inspired by Cesar Chavez’s motto for a United Farm Workers hunger strike in 1972. Excerpts of Obama play throughout the video, with accompaniment from stars like John Legend, Herbie Hancock, Common, Kareem Abdul Jabbar, Scarlett Johansson, Tatyana Ali and Nick Cannon.
