In 1962, Marie Cashman took me and my younger brother on the subway to the WHDH-TV television studios, to appear on the "Bozo The Clown" show.
I was four years old, and my brother was three. Marie was probably fifteen or sixteen, and she had to walk us all the way down the hill from the top of Calumet Street to Huntington Avenue where we took the trolley downtown to switch to the Watertown line and then to a bus to get to the studio.
The memory of the show is mostly a blur.
The clip below is NOT from that broadcast, but rather a very nice quality collection of clips from a 1966 "Bozo" broadcast.
