During the first two seasons there was no theme song! Then show creators William Hanna and Joseph Barbera wrote lyrics for a tune by Hoyt Curtin. The show, which took place in the prehistoric town of Bedrock, was a parody on contemporary suburbia. There were no brakes on cars, just bare feet to slow things down. Cameras were primitive -- birds feverishly chiseled slabs of rock to capture various images. And instead of a garbage disposal, people just kept a hungry reptile under the sink. Still, it was a "yabba-dabba-doo time. A dabba-doo time." In fact, it was a ". . . gay old time!
