So you know how you're not allowed to dance in any bar or club in New York City that doesn't have a cabaret license, and Rudy Giuliani was known for, among other things, closing places down that didn't have the appropriate licenses? Well, you still can't do it, and you won't be able to in the foreseeable future, either. The state Supreme Court ruled yesterday that the 80-year-old cabaret law could be upheld because there's no constitutional right to dance. Oh yeah? Try telling that to, like, Junior Vasquez! The people just want to dance! Enjoy your shuffling-in-place moves this weekend.
