Rock Roll

Prehistoric pop star who sings the big hit "The Bedrock Twitch" in "The Twitch" episode (12 October 1962) of the animated show The Flintstones. Um, it's a parody of "The Twist," but also a swipe at Elvis' redneck accent. He gets sick and Fred looks enough like him to be forced to lip-sync to the song on stage pretending to be him. Hal Smith was the voice of the cornpone-sounding Rock Roll. The song was written by William Hanna and Joseph Barbera.
