question:
Passage: The Bedrock Community Players is mounting A Christmas Carol, and all of the town's citizens are either planning to attend or be involved in the production: Barney Rubble is playing Bob Cragit, with Betty as Mrs. Cragit and his son Bamm-Bamm as Tiny Tim; Mr. Slate is Jacob Marbley; Wilma Flintstone is serving as the stage manager, while her daughter Pebbles plays Martha Cragit; even Dino has a role, playing the Cragit's family pet. It is Fred, though, who has landed the leading role of Ebonezer Scrooge. Unfortunately, he has let his role go to his head, thinking himself a star and spending all of his time rehearsing his lines rather than focusing on his job or family. On Christmas Eve, in his rush to get to work, Fred forgets that he must take Pebbles to "cave care", and later to pick her up from cave care. When Fred arrives at the theater, he discovers a furious Wilma, who breaks down in tears as she tells Fred about his mistake.

Since then, founder Billy Howerdel has started up a new band (Ashes Divide) with drums contributed by Freese. Freese took over from drummer Ron Welty for the recording of the Offspring's 2003 album Splinter after Welty's departure from the band.
