Adolph Menjou was the series host, not simply the narrator. If memory serves correctly, he was introduced in the standard opening as: "And now, here's your host. Raconteur, gourmet, and man about town... Adolph Menjou."
It impressed me as a boy. I didn't know, at the time, that he named names at HUAC.
The series was one in early syndication, and presented a rather literate adaptation of dramatized short stories. Menjou gave it all a nice touch of class.
