Chance the Rapper offered up an awesome dose of nostalgia at the Sasquatch! Music Festival during Memorial Day weekend. Known for his infectiously good vibes on wax and off (he recently led a movement to stop violence for almost 48 hours in his native Chicago), the Acid Rap rapper belted out his version of the theme song from the PBS kids' show Arthur, originally sung by Ziggy Marley and The Melody Makers. No need to be a '90s kid to have this kind of wonderful day. Watch Chano serenade the crowd above.
