Yes, I remember the Jerry song very well and taught it to my four or five year old in the mid fifties. We lived in Saskatchewan where she attended a Montessori School. It is interesting to me as an octogenarian to see the development of children's literature. As a child growing up in the depression, we had no books but stories were handed down by parents or relatives and included a lot of vocal sounds. I especially remember things like, Little Red Riding Hood and the the fun parts of, What big teeth you have, Grandmother/the better to eat you my dear sort of things. My children had books that were read to them along with little rhymes and songs. My grandchildren (l980's) had the books, plus videos such as LADY AND THE TRAMP, SESAME STREET BARNEY, etc. Now my great great grand daughter lives in the big city of London, UK and and has all of the above plus videos of her reading, dancing singing.
