Premise: Kurt Vonnegut's God Bless You, Mr. Rosewater is a 1979 musical that marked the first collaboration of composer Alan Menken and writer Howard Ashman. Based on Kurt Vonnegut's 1965 novel of the same name, the musical tells the story of Eliot Rosewater, a millionaire who develops a social conscience and creates a foundation to improve the lives of the citizens of an impoverished Indiana town.
Hypothesis: A Vonnegut novel was made into a musical more than a dozen years after it was published.
