On Sunday October 26th, Cartoon Network’s Boomerang will be hosting a marathon of the best musical moments of The Flintstones, called Bedrock ‘N’ Roll. The day from 8 AM to almost midnight, will showcase 15 of the series favorite episodes. Through out the shows, be on the lookout for (or have your parents be on the lookout for) a number of special guests that appear, including Ann-Margaret, James Darren and Hoagy Carmichael. …at least I can recognize Fred and Wilma! Check out the classic show intro, below!
