Another Hanna-Barbera classic cartoon, but this one goes back in time to the stone age with the Flintstone family. The opening theme, again from Hoyt Curtin, mirrors 'The Jetsons' in the way it introduces viewers to the characters and their way of living with a tune that's done in traditional grand bandstand style. 'The Flintstones' aired from 1960 to 1966.
