SPECIAL PREMIERE: As a closing celebration for the audacious Crazy Ex-Girlfriend, which has been crazy enough to include original musical production numbers in every episode, the series finale is followed by a musical encore – which sort of makes sense. This one-hour special presents members of the cast revisiting numbers from the show’s four seasons, recreating or revising the original choreography, in a concert setting before an audience. The song titles alone will suggest what people who never watched the series have been missing: one medley alone, set on a red bed, cherry-picks several sex-related musical numbers from the show’s history, including “Strip Away My Conscience,” “Let’s Have Intercourse,” and “Period Sex.”
