William F. Buckley's column, "The Laughter of Archie Bunker" (June 26, 2001) has Carroll O'Connor telling Buckley a story in 1976 about seeing Romano Mussolini, a jazz pianist and son of Il Duce perform at a club in Rome. O'Connor's friend "Abe", after a few drinks, leans over to Romano and says, "You know, that was a hell of a thing they did to your father!"
Billy Crystal used a similar story with Ben Webster saying, "That's a drag what they did to your father." in a standup routine on Saturday Night Live in 1975. I've also heard it with Chet Baker delivering the punchline as, "Sorry to hear about your dad."
Mussolini did have a son Romano, born in 1927, who became a jazz pianist after the war. That much we know is true. Do you think Buckley was snookered by O'Connor?
