Schoolhouse Rock, a pop culture phenomenon over the past four decades, comes to the area in its latest incarnation as an all ages musical, to be staged August 10-18 in the Players Club of Swarthmore’s Summer Children’s Series. Based on the Saturday morning cartoon series seen on ABC-TV from the 1970s through the 1990s, Schoolhouse Rock Live! teaches history, grammar, math, and more to a whole new generation through hit songs including “Conjunction Junction,” “Just a Bill,” “Interplanet Janet” or “Three is a Magic Number.”
