Donald 'O Connor starred opposite a Talking Mule in 6 (Yes, 6!) very successful series o comedies. When Mr. O'Connor got tired of seeing the Mule get more fan mail then he did, he called it quits. To the rescue (?!) came Mickey Rooney as the new owner pal of Francis. Gone was the actor who supplied the voice of Francis Chill Wills. In his place, came voice master Paul Frees. Who did a very good job of approximating the original voice. Un-fortunately, the audiences of the time did not like the changes and this was the last of the classic series made.
