This was probably the late '80s. Dave and I were seated at the same table for the end-of-the-year LPGA Awards Luncheon that was always held in New York City. One year, as it was breaking up, Dave says to a group of us, "Let's go over to Mickey Mantle's for a drink." A group of five or six of us walked over, and as we're nearing the entrance, Robert Merrill, the famous opera singer, is on his way out. Dave and Robert stop to chat right there on the sidewalk outside the restaurant, introductions are made, etc.
After a few minutes, some passers-by recognize Robert Merrill and stop to ask for autographs. A few more minutes go by, a few more people stop, and pretty soon there's a group of 15 or so. A couple in their 60s that were probably from Iowa or Nebraska (he's wearing a jacket with the name of an animal feed company on it) stop to try to peer around the heads of the group to see what all the fuss is about. He elbows his wife and says, "Look, Mel Torme!"
Dave was first-class. RIP.
