Hanna-Barbera Scooby-Doo...Mystery Comics #29

In "The Haunted Riverboat," the gang takes a mysterious trip down the Mississippi aboard the Moonglow, a paddle-wheeler owned by Fred’s history teacher, Mr. Hull. As Shaggy and Fred don crew uniforms and the girls slip into period attire, a whisper from the boiler room hints that the crew knows more than they’re saying—especially when Fred picks up a news report about a gangland boss on the loose.

In "The Boogie Man," the gang finds themselves at a lively juke joint in Nashville, where Scooby-Doo’s clumsy dance move sends coffee flying onto the new denim suit of local legend Don Malarkey—only to earn a surprising smile when Malarkey recognizes the dog as a famed ghost breaker. Now, with musician Jimmie Majeski haunted by the ghost of the late Charlie Crockett, who insists the tribute album must be abandoned, the mystery thickens as the master tapes vanish once more—leaving the gang to uncover who’s really behind the phantom interference.
