I knew every one of 'em.
My parents took me to see Bozo when he made a personal appearance,and they told me that Bozo had held me in his arms.(I have no memory of that...I was only a baby...and,of course,NEITHER of my parents thought to take a picture! I have to take their word for THAT one).
But I DO remember seeing both Willie Whistle AND Romper Room's Miss Jean at the Christmas Parade in Quincy.(That must have been around '69 or '70).Two things stand out in my memory about that:
1)- Santa Claus was supposed to show up at the end of the parade,but never made it,
and
2) - My dad making an observation about how well-developed Miss Jean was.Now all these years later,I must agree! ;)
