Parcel from America subtitles itself “The Irish Musical,” and begorra, is it ever. A near-original, loosely adapted from a story by Tomáseen Foley, with music by Malcolm Hillgartner and Kevin Corcoran and book by Hillgartner, Jahnna Beecham, and Michael J. Hume, it wears its Irishness on its sleeve—not to mention on its brogues, its Aran sweaters, and set designer Harry Feiner’s evocative County Limerick backdrop. A placid evening, with goodhearted small-towners looking after one another and banding together as a community when one of its own is suffering, it’s a feel-good show, and a welcome one.
