Today’s the last day of rehearsal for dozens of kids in Knoxville as they get set to perform tomorrow. The Missoula Children’s Theatre is in town this week helping kids get ready for a performance of Hansel and Gretel. The famous fairy tale of children in trouble has been set to music, with professionals teaching kids of all ages the basics and some advanced points of the theatre. The performances are set for 1pm and 4pm on Saturday at Celebrate Community Church.
