Joe, of course, has the most famous number from “Show Boat”, “Ol’ Man River”. It is worth the price of admission to hear Philip Boykin sing it. Luckily, he sings it several times. With a full bass voice, and not one gravelly bottom note, Boykin exudes all the sweat and strain Joe sings about while also conveying as an actor Joe’s choice to roll along just like the Mississippi River the song hails.
