Ben Vereen, Lorne Green, Dan Blocker, Michael Landon, Mickey Haggarty, Walt Disney, Mr. Nash (did many of the Disney character voices), Bill Cosby,
Molly Hatchet group, Debbie Boone, Charlie Daniels, The Marlboro Man (the guy on the Marlboro billboards years ago). He and my dad used to fly homing pigeons in So. Cal., James Garner, Annette Funicello, Anna Maria Albergetti, Mickey Rooney, Jack Parr, Soupy Sales, Roger Barris, Seward Johnson (sculpter and one of the Johnson and Johnson family), and ...ready for this. Chucko the Clown. I think there's a few more but I can't think of them at the moment.
My dad and uncle had an exotic animal import business in So. Cal for many years. Back before it was illegal to have them. That's how I met some of these folks.
Just remembered another:
Dick Smothers of The Smothers Brothers made a movie in which he played a limosine driver. I was working for a limo company at the time and they rented a limo for two days to do some filming in Princeton NJ. I was his 'stand in' driver for the scenes that didn't show his face. I never did see the movie. LOL
