FEATURED EVENT - MCSP Presents the Last Curtain Call at St Catherine of Siena:

 In Last Curtain Call, the small-town community theater is clinging to life — and sanity — as an unforgettable band of misfits scrambles to stage a show that might save their beloved playhouse. With a hopelessly optimistic director, a chronically frazzled producer, a gossiping chorus that won’t stop singing, a grumpy tech crew, a haunted actor with a past, and a props guy whose creations explode more often than they work, disaster is always one rehearsal away. Hearts will tangle, egos will clash, secrets will erupt, and just when the curtain seems destined to fall forever… this chaotic little troupe discovers they might just have one last miracle left in them.

   When:   Evening shows: Jan 30,  Feb 6, 7  CURTAIN: 8PM       Matinees  Jan 31, Feb 1, 7 at 1:30 pm.  Tickets can be purchased on the MCSP website - click on the picture to access!
