No Cheap Trick? No Foo Fighters, no power pop, no “Mighty Wings” playing at the end of Top Gun…. Imagine! All these things are easy to mock, but they bring a lot of joy to a lot of people…exactly what the band has been doing since 1974. The lineup at this Capitol Theatre showing is mostly original—handsome Robin Zander and Tom Petersson remain, along with cardigan-wearing weirdie Rick Nielsen and his son Daxx.
