Clown was a Learning Corporation of America title which was originally part
of Columbia Pictures. It has a lovely music score but entirely non-verbal.
It dates from 1970 or 1972 is 15 minutes in length. I had the title in my
16mm. collection at Los Angeles County Public Library.
Barbara at Phoenix may have it since they purchased Coronet which I believe
included LCA titles. If you wish, I can fax you a complete description and a
study guide which I have from that period of time. Let me know.
