The clown on the right is Chuck Sidlow. I'm not positive about the ID of the other three. Maybe Greg can ID them before I embarrass myself with a guess based on program pictures.
The gentleman in the center is Dick Van Dyke. After reading his less-than-flattering assesment of the art of circus clowning in Diane Keaton's recent book CLOWN PAINTINGS I set aside my feelings about his television and film work in the 1960s and now feel that Mr. Van Dyke has become nothing less than a complete and total Dick.
I'm amazed that someone could insult the work that professional circus clowns do after turning in the putrid performances he did in the CBS Television CLOWN COLLEGE 20TH ANNIVERSARY Special.
Yes sir, quite the Dick.
