Claim: Crystal Tipps and Alistair which has no dialogue was created by Graham McCallum and the animation was done by Richard Taylor Cartoons
Evidence: It was created by Hilary Hayton and Graham McCallum. The animation was done by Richard Taylor Cartoons, who were also contracted to make the Charley Says and the Protect and Survive public information films for the Central Office of Information. The series has no dialogue but rather is accompanied by a full musical soundtrack composed by Paul Reade; however, when shown on Captain Kangaroo in the U.S. in the 1970s the series did have voice-over narration by Cosmo "Gus" Allegretti in his high-pitched "Mister Moose" voice.
