Today in 1946, the second Broadway revival of Showboat opened at the Ziegfeld Theatre, and ran for 418 performances. Show Boat is a musical in two acts with music by Jerome Kern and book and lyrics by Oscar Hammerstein II. It was originally produced in New York in 1927 and in London in 1928, and was based on the 1926 novel of the same name by Edna Ferber. The plot chronicles the lives of those living and working on the Cotton Blossom, a Mississippi River show boat, from 1880 to 1927. The show's dominant themes include racial prejudice and tragic, enduring love.
