Adam10, the highlights were the first part of the show with the Chicago Symphony Orchestra before he came out to sing/chant/groan over their playing. Half of our group hated his voice, a couple that were with us love him. He definitely has his fans, though. The highlight of Ravinia is that you can bring your own food and beverages to picnic on the lawn with live music in the background. We have a decent number of free passes and this show took place on an evening with perfect weather, so we went.
