Here was a Broadway show that proved a sell-out for months and is now on the road, making the nation once more Mark Twain conscious. And the man who did the impersonation of Mark Twain, and who selected and prepared the extracts from Mark Twain's writings that provided the substance for the readings, is Hal Holbrook. In this he has told his own story:- fresh out of college and newly married, he and his bride barnstormed high school auditoriums and small towns of the mid-west with a show for two. Later, they came to New York, had night club spots, off Broadway readings, radio and TV shows- and all the time the Mark Twain material was being worked into what became last season's surprise success. The personal story of Hal Holbrook is one third of the text; the balance is the Mark Twain material, woven together into the unities that were drawn on for the Holbrook show. This is good theatre- as well as good Mark Twain.
