The Ziegfeld Theatre opened in February 1927 with Ziegfeld's production of "Rio Rita", which ran for nearly 500 performances. This was followed by "Show Boat", a great hit with a run of 572 performances. This musical, which concerned racial discrimination in the South during the late nineteenth century, was a collaboration between Ziegfeld, Urban, and composer Jerome Kern. The musical has been revived four times on Broadway, winning multiple Tony Awards. The score features several classics such as "Ol' Man River" and "Can't Help Lovin' Dat Man".
