Here's a Rankin-Bass production that somehow has been lost to the mists of time, having not gotten as much airplay as the rest of the R-B line. Cricket on the Hearth is based on a story by Charles Dickens ("A Christmas Carol"), and, as with virtually every other R-B special, is star-packed, with an all-star cast headlined by Danny & Marlo Thomas. Marlo was starring in That Girl around this time, so this might've aired on ABC, I'm not sure. The cast also features actor-singer Ed Ames (Daniel Boone), Abbe Lane, and Roddy McDowell as the titular cricket. Starwarsmarveldc uploaded this clip to YouTube:
Seeing as how I've never seen this show, I cannot rightly give it a rating. It is, however, available on DVD in a compilation package.
