Chance The Rapper won over every '90s kid when he performed a cover of the "Arthur" theme song at Sasquatch! Music Festival over Memorial Day Weekend. Originally performed by Ziggy Marley for the PBS children's show, "Believe In Yourself" should not be confused with the theme song to "Arthur," the 1981 romantic comedy starring Dudley Moore and Liza Minnelli. Sure, that track won an Oscar for Best Original Song that year, but did Chance The Rapper and his band The Social Experiment make a Washington crowd go crazy with it in 2014? No he did not.
