The sister and BIL of one of my best friends were very wealthy and owned Jack Benny’s old house in Hollywood. Their three best friends were Gene Hackman, Gene Wilder and Johnny Carson. My girlfriend used to visit out there several times per year. She said Johnny Carson practically lived at her sister’s house because he loved their tennis court. He was a tennis maniac. She also said he was very introverted in real life. He was a nice guy but very quiet. Nothing like on TV.
Johnny’s introversion was in large part the reason that when he retired from the Tonight Show, he retired almost completely from show business. I guess he did a little Vegas stuff, but not much, as I recall.
I remember seeing Carson in the crowd every year at Wimbledon.
