Jack Benny Program - S14xE20 - The Final LeBlanc Sketch

In desperation, a psychiatrist phones Jack for his help with a distraught patient. An amnesiac with a violin has been found on the street, and he's bitterly muttering Jack's name - over and over. Jack identifies him as his long-time, long-suffering violin teacher, Professor LeBlanc, who reveals he couldn't lose his hearing, so he lost his mind.
