The Improv Asylum on Hanover Street in the North End is producing a new kids show that goes live this Sunday. They are offering free tickets to the first show (as a way to get the word out) and would love to fill it with North End families.

The show is called Frannie and is a musical parody of Annie. It has a lot of improv structures in it and audience participation. It is an all-ages show, but recommended for 5 and older. (Ideally 8-10 year-olds would love it.)
