We've gone to them for several years-guess they bring back memories of our "concert" years-back when we were teenagers. We love them! If I remember, each concert that I've been to lasted about 30 minutes. I'll tell you, though, for those of us who "remember", it seems strange to listen to Steppenwolf do "Born to be Wild" as you sit in Epcot surrounded by kids, sipping a Diet Coke!
