What are you doing on this first Saturday of Spoleto? Chances are, you’re probably not seeing The Medium, The Red Shoes, and Karrin Allyson, unless you already have tickets to those shows. They have limited availability today.

Tonight’s Improv Comedy Marathon is full as well, and so is Duende. What can we say? We warned you.

As of this hour, there is one ticket to tonight’s 7:30 p.m. performance of Race. There are two tickets left to How to Eat Like a Child on June 8 at 5 p.m., and four to five tickets left for The Gentleman Pirate (May 29 at 5 p.m.), John Street Jazz (June 5 at 5:30 p.m.) and today’s 4 p.m. performance of Superior Donuts.
