 This year, they'll perform with a special variety of guests like Bluey and Princess Tiana. Also, Brian Agelmeyer, a drama teacher at the school district in Clayton, will narrate a choose-your-own-adventure song, and the audience will get to vote on the outcome of the story. Tonight's concert, Riverview Park, 7.30 p.m., and then at Haskell Park Sunday at 7.00. Again, both concerts are free.
