Stamps, letters, and packages hardly seem the stuff of energetic musicals. But then, when has the Buntport Theater Company ever tackled a traditional topic? In its newest song-and-dance show, which opens this Friday, the unconventional theater company weaves together the lives of its four protagonists via the postal service. Ultimately, envelopes and postmen shape the futures of each of the characters. If this Buntport show is like the last, the outrageous writing and acting should have you laughing nonstop. Fri, Feb. 27, 8 p.m. Buntport Theater, 717 Lipan St., 720-946-1388, $16
