I grew up in Hyannis on Cape Cod, so between the Kennedys and people doing summer theater/concerts, I saw a lot when young...
Judy Garland
Liza Minelli
Lorna Luft (Liza's half-sister)
Jane Fonda
Mitzi Gaynor
Kennedys: President Kennedy (patted me on the head when I was 4!), Jackie, Caroline,
JFK jr (HUNK!), Aristotle Onassis (liked Heineken), Ethel, Joan and all their kids, Bobby Shriver, Maria Shriver, Arnold; we belonged to the same golf club as the Kennedys and went to the same church, so we saw them every summer all summer long, so it was really not a big deal. Sailed with Ted once; what a great guy, loved life and was very funny.
Ricardo Montalbon(very charming)
Andy Williams
Leonard Nimoy
Diana Ross
Carol Burnett
I know there's more but that's what I remember right now.
