There is some pretty spectacular musical theater on stage right now in Santa Barbara in a surprising location. For the bargain price of $10, you can treat yourself to two hours of Vegas-wattage, Broadway-bound rising stars hitting it out of the park. The Santa Barbara High School Theater is staging Spamalot, lovingly ripped off (as they put it) from Monty Python’s Holy Grail, totally amped up, dressed up and repackaged into a raucous show with something on offer for everyone.
