I don't know why you might think his injury was made up or a ruse to get PR. Back injuries and the resulting pain are nothing to laugh about. Bart's back was out...just as Nathan Lane's back was out. Troupers get back in the saddle as soon as physical therapy and other therapies give them the ability to work. It doesn't mean his back is not hurting. If they were able to move things around (by chiropractor or other technique)and get his back in shape, he is probably don't much better. He is, after all, a dancer and is in pretty good shape. I wish him the best with the back injury. Often you have a recurring problem once you have had one bout with a herniated disc.
