I met a few people when I was young, but failed to 'appreciate' their celebrity status. In the very ealry 70s (72?) the Bee Gees stayed at my parents hotel. And at the same time, Bob Moose, pitcher for the Pittsburgh Pirates, was a friend of my parents and visited often. He died in a car accident in 76, but was known as the only Pirate to pitch a no hitter (against the Mets) and also famous for a wild pitch that sent the Reds to the World Series (I think 72).
Since I'm not a BeeGees or basefall fan, this was all lost on me. But I was really into CP, and remember ordering from World Insectivorous Plants!
Oh, one more baseball celeb story. My company hired Don Sutton, Hall of Fame pitcher for Dodgers, to autograph baseballs. I got one for my son. I was foolish enough to tell him that I never heard of him. His response? "That's OK, Joe, I never heard of you until today, so we're even". He said it politely and with good humor. I most assuredly did not win points with the guys at the convention on that one.
