Peter Cetera, where are you when we need you most?

Went to see a Chicago cover band last night. They were NOT good. Now, Peter Cetera has a voice that is hard to replicate. I get it. But man. we made it through the first set and I couldn't take a butchering of "You're the Inspiration," so we left. Not a "Hard Habit to Break," as it turns out. We could "Look Away." (Okay, I'm done. Plus I don't know any more Chicago songs.)
