The Saturday morning educational cartoon series is now the basis for Schoolhouse Rock Live! JR. A loose, revue-like musical which follows Tom, a young school teacher, who is nervous about his first day of teaching. He tries to relax by watching TV, when various characters representing facets of his personality emerge from the set and show him how to win his students over with imagination and music. Memorable songs such as "Just a Bill," "Lolly, Lolly, Lolly" and "Conjunction Junction" bring his lesson plans vividly to life.
