The Adventures of Young Indiana Jones: Mystery of the Blues.

Going to college and working in a seedy speakeasy bring Indy into contact with jazz great Sidney Bechet, who teaches him how to play the blues. Unfortunately, he also crosses paths with up-and-coming thug Al Capone and it's only with the assistance of his dorm roommate, future Untouchable Eliot Ness, that Indy is able to solve a vicious murder and prevent himself from ending up in a pair of cement overshoes.
