My wife and I saw Styx and REO Speedwagon last nite at the Pikeville Expo Center. It was awesome! The opening act was Bo Bice "yawn".
When I said "Styx" I should have said, "Tommy Shaw, JY, and three other dudes". Though the other dudes are very, very good, the absence of Dennis DeYoung and the Panozzo brothers made Styx seem more like a new band.
In the world of rock musicians, Tommy Shaw is about as close to the genuine article than you can get.
REO was really good, too. Kevin Cronin's voice was a bit thin and he has lost some of his range. But he was still very high energy and worked very hard.
