In the season finale of IN THE SPOTLIGHT, we take a ride aboard SHOW BOAT. The 1927 Jerome Kern and Oscar Hammerstein II epic arose out of a sea of operettas and revues to be the first true musical - or was it? We look at the show's fascinating history and complicated legacy, dive into how "Bill" went from being a comedy number in another show to a devastating torch song with only a few tweaks, and celebrate the show that just keeps rollin' along almost a century after it changed theater forever.
