The Fantasticks, the self-proclaimed " world's longest running musical," centers on "one young couple, two 'feuding' fathers and an infinite love that transcends over time" as the play offers up "a world of moonlight, magic and memory." The Great Lakes Theatre production of the play opens tonight at 7:30 at the Hanna Theatre, where it runs through May 29. Tickets are $15 to $70. (Niesel)
