A CONNECTICUT YANKEE (Rodgers & Hart) More than a half-century before Monty Python’s Spamalot, the knights of King Arthur’s Round Table were already on Broadway, singing and dancing in Rodgers and Hart’s delightful musicalization of Mark Twain’s classic tale A Connecticut Yankee in King Arthur’s Court. This 1955 television production boasts a cast led by Eddie Albert, Janet Blair, Gale Sherwood, and the Boris Karloff as King Arthur. 77 min.
