Far Too Many Melodic Songs For One Show
Having seen "Showboat" on stage, I can testify that some songs were shortened to fit the time slot of this movie.
Both "You Are Love" and the great "Old Man River" are shorter in the movie than the stage versions. That's understandable, because the stage version is too long.
When you add "Make Believe", "Bill", and "Can't Help Loving Dat Man", it's clear that there are too many great songs for one show. Five standards in one show is too many.
The musical "Cats" had only one standard. "Les Mis" had two. Audiences today don't want more than that.
Kern and Hammerstein could easily have eliminated three of these standards and made one or two more musicals with the extra songs.
