In the concluding episode, Neil explores why musical theatre is thriving in the 21st century. He charts the rise of the 'megamusical' phenomenon, with shows like Cats and Les Miserables, learns the behind-the-scenes story of how Disney transformed The Lion King from a cartoon into a record-breaking stage success, and sees how musicals have captured contemporary life in shows like Rent and Avenue Q. Neil recreates classic numbers to reveal the secrets of their songwriting, including The Rocky Horror Show's Sweet Transvestite, Don't Cry for Me Argentina from Evita, and Les Miserables' Empty Chairs at Empty Tables. Neil meets a host of top musical theatre talent, including master lyricist Tim Rice, Lion King director Julie Taymor, and leading composers Alan Menken (Beauty and the Beast) and Robert Lopez (Avenue Q and Frozen).
