Among the bonus features on the fourth-season Flintstones DVD set is “The Legendary Music of Hoyt Curtin,” in which I appear, talking about the great composer of all our favorite Hanna-Barbera cartoons of the 1960s. Curtin was the good-humored, talented jazz composer whose music helped to make The Flintstones, The Jetsons, Top Cat, Jonny Quest and so many others such animation classics.
