The cast of the Marriott's recent version of The Music Man just falls flat. Either they can sing but not act, as in the Professor Harold Hill actor or they can act but cannot sing as in the actor who portrays Marion. There is no chemistry, flirtation, humor between Professor Harold Hill and Marion the librarian. There is also no set and not many costume changes. And yet, you can still enjoy the beautiful music and the sweet story of a small town that comes together.
