PBS is reviving “The Electric Company” and updating it for today’s kids who are fed a diet of hip hop and “High School Musical.” For me, the original show was notable for having an actual, honest to goodness Asian person in the cast, June Angela (with the amazingly long hair). In a DVD interview, she recalls that the casting call only went out for “black and white” children but her agent asked them to see her anyway. Angela stayed with “The Electric Company” through its entire run, the only one of the Short Circus kids to do so.
