A few. Some planned & some by chance.
As one of those "child prodigy" musicians, I had to take photo sessions with some celebrities - George Burns, Debbie Reynolds. Ms. Reynolds wasn't shy, but I was - at 16. Before the photo, she grabbed my arm, put it around her & said, "Hey...you NEVER stand next to a beautiful woman without touching her." LOL!!!
I was at the TV studio for more photos with the cast of "Green Acres." I've always loved animals, so when I was wandering around the studio, I found that huge pig that was on the show. I sat on the floor & he sat next to me. After an hour, the photographer found me & said, "Where the hell have you been; we've been looking for you for an hour; ya know how much time costs here?" Well....no, I didn't know, & didn't care; I'd rather spend time with an animal than most people, anyway.
When I was around 20, I drove to Las Vegas with friends. We arrived at 2am & were walking around the casino at Ceasar's Palace. I saw Lorne Greene chatting with George Burns. A couple of teen-age girls walked by & one of them said, "Ooooh, George, you're so sexy." Lorne said, "Hey....what about me?" All of us LOL'd.
23 years ago, I flew to Youngstown, OH for my cousin's wedding. The flight stopped in Houston, TX for a couple of hours. I was in the restroom washing my hands & Brian Dennehy walked in. We chatted for a minute. I remember thinking, "Even when he smiles, he looks like he's angry."
I was on a lunch break from work & I was sitting in my car in front of a health food store. I noticed a guy parked next to me sitting in his car. He was slumped down in the seat with his head down, also eating. A couple of girls walked by his car & started giggling; they recognized him - Dennis Weaver. He signed a napkin for them, then looked at me, frustrated. I said to him, "Well, nice try at not being recognized."
I was in a restaurant with my girlfriend. David Soul walked in, dressed exactly as he dressed on "Starsky & Hutch;" that brown jacket & blue jeans. My girlfriend really liked him & she wanted an autograph. I said maybe she shouldn't bother him. She couldn't resist. He was really nice; he autographed a napkin & wrote "Much Joy, Andrea" on it.
