Weren't they great? I'll never forget M. Bentine had a kids TV prog. I must have been about 8 He had this string puppet called Dreary Weary, which was very crudely made, and kept coming apart to a background commentary like Andy Pandy. Eventually the arms were on one side of the screen ,the head was on the floor, and the legs were going out both sides. It must have been funny to remember it so long ago.
