David Nail has been forced to cancel shows this week for the first time in his career. The culprit is a nagging sore throat that won't go away.  He writes on Twitter, "They say I'll never get better unless I really rest!" David expects to do more than just make up these shows, adding, "We'll find a way to make it better than had been planned!" David's canceled shows this week include dates in Mount Laurel, New Jersey; Raleigh, North Carolina; and Harrisburg, Pennsylvania.
