“The two great rules of history are you shouldn’t fight a landwar in Asia, and you shouldn’t make cops sing on television. Those arethe two things we’ve learned in our time on the planet.” Or so says John Romano, an exec producer on Patrick Swayze’s upcoming A&E series The Beast who also happened to work on Steven Bochco’s legendary musical drama Cop Rock, which ran for 11 episodes on ABC in 1990. “It’s legendary. It’s legendary for lots of reasons. That’s a very pleasant word,” Romano told us recently. “It’s funny, whenever I run in to Steven Bochco we always have a good laugh. We’re very proud of it. There were great episodes. We had done Hill Street Blues together, so we had a kind of sly, ironic musical retake of Hill Street in our minds. We had fun.” (Watch their farewell song below, and more clips after the jump.)
