Billy Joel vows that he will do a concert a month at Madison Square Garden in New York until fans stop coming. The 'as long as there is demand' commitment will open with a previously announced date on January 27. Joel has made close to 50 concert appearances at the landmark arena in Mid-Town Manhattan, including a run of a couple of dozen sold-out shows in 2006. His Tuesday press conference announcing the open-ended series in New York even drew an appearance by NY Gov. Andrew Cuomo.
