"Mark Twain's Life on the Mississippi" is a celebration, in Twain's own words, of a young country boy's transformation into a Mississippi River steamboat pilot, "the only unfettered and entirely independent human being that lived on the Earth."  Drawing mainly from the autobiographical portions of "Life on the Mississippi," the show presents a master storyteller recounting the most joyous time of his life, the people he met and the events, both happy and tragic, that set young Sam Clemens on the road to becoming Mark Twain.
