The Rolling Boulders had bigger hits than the Rolling Stones.

The Rolling Boulders. Sounds like a band from Bedrock, as in the Flintstones. They actually did have a 60s-era band on in one episode: The Beau Brummelstones, a play on the group, The Beau Brummels, who had the 60s hit "Laugh Laugh". They even had them performing that song.
